This Week's TV: Welcome back Fringe and Supernatural. Plus 5 Brand New Shows!

The fall season is in full swing this week, with tons of TV shows returning — including the season premieres of Fringe, The Big Bang Theory, Community, Supernatural and several other shows. But there are also a number of series premieres, including Person of Interest, the creepy new show from Jonathan Nolan and J.J. Abrams.

Click through for all the scoop, including clips from Eureka, Warehouse 13, Star Wars: The Clone Wars, Fringe and several other shows.

Today:

Once again, Cartoon Network is depriving us of new Adventure Time. Instead, there's just a new Johnny Test at 7 PM, in which: "Johnny gets a key that opens any door and lock in the city. Everyone in town discovers what he has, and wants it for themselves!" That's followed by the season premiere of Regular Show at 8:15 PM, and a new Mad at 8:30 PM. Check out a fresh clip from Regular Show.

Syfy has the season — but not series — finale of Eureka at 8 PM, "One Giant Leap." Here's what Syfy tells us about the new clip from the episode:

Carter and Jo make a stop near a creek with Dr. Plotkin to check in on Taggert. Plotkin and Taggert continue their feud as Plotkin is there to pick up a scientific instrument that belongs to him, while Taggert is explaining why his own research benefits all life on the planet. All of a sudden, as Plotkin is retrieving his planted rod, Taggert's truck is mysteriously sucked into the sky.

That's followed at 9 PM by a new Warehouse 13, "Insatiable," in which:

While Myka and Pete deal with a zombie plague spread by a taco truck, Claudia tries to reach Jinks.

Taco truck zombies? That's almost as ridiculous as trout zombies.

And then at 10, Syfy has a new Alphas, "The Unusual Suspects." Protect yourself from accidentally seeing any of the Charlie Sheen roast by watching the Department of Defense arrest Rosen and his team, on the suspicion that one of them is a traitor.

Also at 10 PM: the season premiere of Castle on ABC, which we mention only because it's Nathan Fillion and often contains copious nerd in-jokes.

Plus there's another episode of MTV's cops-vs.-the-undead show Death Valley at 10:30 PM, "Two Girls, One Cop."

Tuesday:

Cartoon Network is serving up new episodes of Scaredy Squirrel and Looney Tunes Show, starting at 7 PM.

At 10 PM, CBS has the season opener of Unforgettable, which is sort of an edge case. It's definitely a show about someone who's non-neurotypical. Here's the description:

UNFORGETTABLE stars Poppy Montgomery as Carrie Wells, an enigmatic former police detective with a rare condition that makes her memory so flawless that every place, every conversation, every moment of joy and every heartbreak is forever embedded in her mind. It's not just that she doesn't forget anything - she can't; except for one thing: the day her sister was murdered years ago. Since then, Carrie has tried to put her past behind her, but she's unexpectedly reunited with her ex-boyfriend and partner, NYPD Detective Al Burns (Dylan Walsh), when she consults on a homicide case. His squad includes Det. Mike Costello (Michael Gaston), Al's right-hand man; Detective Roe Saunders (Kevin Rankin), the junior member of the team; and Detective Nina Inara (Daya Vaidya), a sassy, street-smart cop. Surprisingly for Carrie, being back on the job after a break feels right. Despite her conflicted feelings for Al, she decides to permanently join his unit as a detective solving homicides - most notably, the unsolved murder of her sister. All she needs to do is remember.

Wednesday:

At 10 PM, Science has another episode of Dark Matters: Twisted But True, hosted by Fringe's John Noble. Segments include "Tripping with Uncle Sam" and "My Hand is Killing Me." Just two more days until actual Fringe.

Thursday:

There's another new WTF-a-thon, with The Vampire Diaries on The CW at 8 PM, "The Hybrid":

Klaus (Joseph Morgan) puts a plan in motion that will give him even more power, but even with the unwilling participation of werewolf Ray Sutton (guest star David Gallagher), things don't go exactly as Klaus had planned. Damon (Ian Somerhalder) and Alaric (Matt Davis) reluctantly go along with Elena's (Nina Dobrev) new strategy to find Stefan (Paul Wesley), leading Damon into a dangerous fight with an unexpected enemy. Jeremy (Steven R. McQueen) turns to Matt (Zach Roerig) for help as he continues to try to understand what the ghosts from his past want from him. Unaware that Caroline (Candice Accola) is in need of his help, Tyler (Michael Trevino) faces an emotional confrontation with his mother (guest star Susan Walters).

Also at 8: NBC has the season premiere of the frequently nerd-tastic Community, "Biology 101."

THE GANG REUNITES AFTER SUMMER BREAK WONDERING IF PIERCE WILL BE BACK AT SCHOOL: DEAN PELTON RETURNS FROM "DEAN CAMP" WITH VIGOR — JOHN GOODMAN AND MICHAEL K. WILLIAMS GUEST STAR. As the Greendale study group gathers in the library, they wonder whether they will see their old friend Pierce (Chevy Chase), who left the study group in a huff after last spring's paintball game. Jeff (Joel McHale) quickly butts heads with their new biology teacher Professor Kane (Michael K. Williams, "The Wire,") and is kicked out of class — leading to a crisis within the group about whether they will all stay together. Dean Pelton (Jim Rash) is feeling empowered after a summer at "Dean Camp" but finds a new nemesis in Vice Dean Laybourne (John Goodman), dean of the highly regarded Air Conditioning Repair Annex at Greendale.

Also at 8, there's the season opener of The Big Bang Theory on CBS:

"The Skank Reflex Analysis" THE GANG DEALS WITH THE AFTERMATH OF PENNY AND RAJ'S NIGHT TOGETHER, ON THE FIFTH SEASON PREMIERE OF "THE BIG BANG THEORY," THURSDAY, SEPT. 22 Emmy Award Nominee Christine Baranksi Reprises Her Role As Leonard's Emotionally Distant Mother. Penny worries that she's screwed things up permanently with her friends, while Sheldon takes command of the paintball team.

That's followed at 8:30 by a second new Big Bang Theory. Here's a sneak peek.

But there's also a fourth option: the series premiere of Charlie's Angels on ABC, which we only mention because: 1) It's probably going to have some ludicrous spy gadgets and plot devices, like most spy-fi shows. 2) The writing staff includes Javier Grillo-Marxuach of The Middleman fame, and Douglas Petrie of Buffy the Vampire Slayer fame. Probably worth at least keeping an eye out to see when Grillo-Marxuach's episodes air.

At 8:30, there's a new Problem Solverz on the Cartoon Network.

Then at 9 PM, CBS has the series premiere of Person of Interest, a new show from Jonathan Nolan (The Dark Knight) and J.J. Abrams (Lost, Fringe) about a supercomputer that can predict crimes. Here's the blurb:

PERSON OF INTEREST stars Jim Caviezel, Emmy Award winner Michael Emerson and Academy Award nominated and current Emmy Award nominee Taraji P. Henson in a crime thriller about a presumed dead former-CIA agent who teams up with a mysterious billionaire to prevent violent crimes by using their own brand of vigilante justice. Reese's special training in covert operations appeals to Finch, a software genius who invented a program that uses pattern recognition to identify people about to be involved in violent crimes. Using state-of-the-art surveillance technology, the two work outside of the law using Reese's adept skills and Finch's unlimited wealth to unravel the mystery of the person of interest and stop the crime before it happens. Reese's actions draw the attention of the NYPD, including homicide detective Carter, and Fusco, a cop whom Reese uses to his advantage. With infinite crimes to investigate, Reese and Finch find that the right person, with the right information, at the right time, can change everything.

Also at 9 PM, The CW has another episode of The Secret Circle, starring Thomas Dekker as a man-witch. It's called "Bound," and here's what it's about:

CASSIE ATTEMPTS TO HAVE A LIFE WITHOUT WITCHCRAFT BUT DIANA HAS DIFFERENT PLANS - In an effort to distance herself from the Circle and establish a normal teenage life in Chance Harbor, Cassie (Britt Robertson) befriends Sally Matthews (guest star Logan Browning), a non-witch. Concerned their powers are getting out of control, Diana (Shelley Hennig) pushes everyone to bind the Circle, but Faye (Phoebe Jane Tonkin) is thrilled with the increase in her powers and refuses to participate, while Melissa (Jessica Parker Kennedy) flirts with Nick (Louis Hunter) despite Faye's warnings. Meanwhile, Adam (Thomas Dekker) fights his growing feelings for Cassie, but circumstances continue to throw them together, forcing Cassie to make a decision.

Then at 10 PM, there's another new Ancient Aliens on the History Channel, "Aliens and Deadly Weapons."

And at 10:30 PM, there's another Archer on FX, "Heart of Darkness, Part 2."

Rex is attacked by Breach while delivering Chinese takeout to hungry Providence Agents. She says that Van Kleiss has an important mission for her in Hong Kong, China that involves an "old friend" of Rex's. Thinking that she means Circe, Rex jumps through Breach's portal to where Tuck, Skwydd, Cricket and Circe are, to warn them of the danger.

And at 7:30 PM, there's a new Ben 10: Ultimate Alien, "Simian Says":

Simian brings a DNAlien Xenocyte to the Arachnachimp's planet and infects all the Arachnachimps until only Simian is left. With the help of Eunice, they attempt to genetically restore the planet's inhabitants.

At 8 PM, CBS has the series premiere of A Gifted Man, its new show about a man whose dead wife helps him be a better doctor. Here's the skinny:

A GIFTED MAN is a drama about a brilliant, charismatic surgeon whose life changes forever when his deceased ex-wife begins teaching him the meaning of life from the "hereafter." Michael Holt is an exceptional doctor who lives a materialistic life of luxury thanks to his work-obsessed career and powerful and wealthy patients; however, Michael's ordered world is rocked when his ex-wife, Anna, an idealistic free-clinic doctor and the love of his life, mysteriously appears to him. In an attempt to go back to his "normal" life, Michael visits Anton, a carpenter who moonlights as a Shaman to try and extract Anna's spirit from his body, but when Anna appears and asks Michael to go to her clinic to help keep it running, he realizes she needs him more now then ever. Curious about Michael's sudden change in behavior is his efficient assistant, Rita, who works tirelessly to facilitate his schedule in order to accommodate his added responsibilities at the clinic. Touched by those in need and accepting of Anna's compassionate "presence," Michael's attitude toward serving the rich and poor is turned upside down, and he begins to see that there's room in his life for everyone.

Also at 8 PM, there's a new episode of Star Wars: The Clone Wars, "Prisoners." And here's a brand new sneak peek!

Meanwhile at 8, there's the season opener of The CW's spy-fi series Nikita, which is just as full of crazy awesome plot twists and improbable plot devices as Vampire Diaries. Here's the synopsis:

Nikita (Maggie Q) and Michael (Shane West) plot to take down Division and Oversight and are prepared to use the contents of the black box to do so. Amanda (Melinda Clarke) is now running Division but Oversight has assigned one of their own, a new agent named Sean (guest star) Dillon Casey), to keep an eye on her. Amanda's first mission is to get back the black box from Nikita, and she enlists Alex's help to do so. Alex refuses until Amanda tells her she will help her find the man who killed Alex's father. Meanwhile, Nikita and Michael find help from an unlikely ally.

Yet another option at 8: Nickelodeon has a Spongebob Squarepants special: "Mermaidman Begins"/"Plankton's Good Eye." We're going to learn the secret origins of Mermaid Man and Barnacle Boy.

And another option at 8 is the season finale of Jurassic C.S.I. on the National Geographic Channel, "Inside T. Rex."

THE FRINGE TEAM TAKES NEW SHAPE AS THE IMPACT OF PETER'S HEROIC CHOICE UNFOLDS IN THE FOURTH SEASON PREMIERE OF "FRINGE" FRIDAY, SEPTEMBER 23, ON FOX.

Assuming his new role as God, Castiel sets out to right some of the wrongs in the world. Dean decides they should bind Death (guest star Julian Richings) and order him to stop Castiel, but the former angel is one step ahead of them, leaving Dean to face a very angry Death. Meanwhile, Sam struggles to deal with the broken wall in his head.

Here's an unsettling sneak peek.

In Morlocks, premiering Saturday, September 24, at 9PM (ET/PT), a scientist creates a time traveling device that transports people into a desolate future overrun by lethal humanoids, the Morlocks. Unfortunately, the creatures figure out how to transport themselves back into present day, triggering a race against time between human and humanoid. Starring David Hewlett and Robert Picardo, Morlocks is a production of UFO Films.

Okay, so the title doesn't actually have an exclamation mark in it, we just felt it needed one. And then the sequel can be called Morlocks Take Manhattan!.
