Today:

Syfy is showing Alphas episodes from 11:30 AM to 10 PM, to get you ready for the big season finale.

Cartoon Network has an abnormally huge burst of animated shows. First at 7 PM, there's a new Johnny Quest, "Johnny of the Deep":

Bling Bling uses a ring to hypnotize Susan to fall in love with him, then whisks her off to his yacht. Johnny and Dukey transform into sharks to search for the ring and destroy it, getting help from a retired underwater action hero.

That's followed by Regular Show at 8:15. Then at 8:30 PM, Cartoon Network has a brand new show, Secret Mountain Fort Awesome, about

a gang of awesome monsters that live deep underground. Shunned by humankind because of their gross appearance and radical behavior, they are forced to live together in a place known only as Secret Mountain Fort Awesome. This mega-rad group does some crazy stuff like steal the sun, fight a heavy metal tooth fairy and take baths with CGI sharks!

And finally, there's a new Mad at 8:45 PM, featuring Cowboys and Aliens and Thundercats parodies. Watch a clip at left.

But also at 8 PM, Fox has the two-hour premiere of Spielberg's huge time-travel/dinosaur show, Terra Nova, "Genesis, Part 1 and 2." Yes, it's two hours devoted to your favorite 1970s and 1980s supergroup. Phil Collins plays himself. Here are the details:

TERRA NOVA follows an ordinary family on an incredible journey back in time to prehistoric Earth as part of a daring experiment to save the human race. The Shannon family joins the Tenth Pilgrimage of settlers to Terra Nova, the first colony established in this beautiful yet foreboding land. Jim Shannon, a devoted father with a checkered past, guides his family through this new world of limitless beauty, mystery and terror. Jim's wife, Elisabeth, is a trauma surgeon and the newest addition to Terra Nova's medical team. Josh is their 17-year-old son who is torn to leave life as he knows it behind; upon arriving at the settlement, he finds himself instantly drawn to the beautiful and rule-breaking Skye. Maddy, Josh's endearingly awkward 15-year-old sister, hopes Terra Nova will give her a chance to reinvent herself. Although Elisabeth's medical training secured the family a spot on the pilgrimage, a secret involving their five-year-old daughter, Zoe, soon endangers their place in this utopia. Upon the Shannons' arrival, they are introduced to Cmdr. Nathaniel Taylor, the charismatic and heroic first pioneer and leader of the settlement. Taylor warns the travelers that while Terra Nova is a place of new opportunities and fresh beginnings, all is not as idyllic as it initially appears. Along with blue skies, towering waterfalls and lush vegetation, the surrounding terrain is teeming with danger - and not just of the man-eating dinosaur variety. There is also a splinter colony of renegades led by the battle-hardened Mira, who is vehemently opposed to Taylor and his leadership.

And then at 10 PM, there's the season finale of Alphas, "Original Sin":

Rosen and his team must choose sides when Red Flag launches a full-out assault on the Department of Defense.

Tuesday:

At 10 PM, CBS has another episode of Unforgettable, a police procedural about a woman who can freeze-frame and zoom and enhance her memories. How on Earth are they going to make this gimmick work in an episode where she's not dealing with a crime she personally witnessed part of? Here's your first clue, in the episode's synopsis:

CARRIE MUST FACE HER PAST WHEN A LITTLE BOY IS THE ONLY WITNESS TO A MURDER. When a young boy witnesses a murder, Carrie must put aside the memories of her sister's death to help him lead the police to the killer.

Ah, little kids. They make everything better.

Wednesday:

Mythbusters is back for its tenth season! The season premiere is called "Bikes and Bazookas," and I'm just guessing that means something will be getting blown up.

In a flashback to Chicago in the 1920s, Stefan comes face-to-face with a shocking chapter from his wild past. After Damon (Ian Somerhalder) gets a tip on Stefan and Klaus' whereabouts from an unexpected source, he and Elena (Nina Dobrev) follow their trail. Back in Mystic Falls, Tyler is concerned about Caroline and turns to Sheriff Forbes (guest star Marguerite MacIntyre) for help.

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

Then at 9 PM, CBS has another episode of Person of Interest, the show about the supercomputer that can predict crimes that haven't happened yet. How are they going to make this premise last more than a few episodes? Here's your first hint, with the synopsis for "Ghosts."

When they are given the Social Security number of a teenager who was killed two years ago, Reese and Finch begin to question the infallibility of The Machine. Meanwhile, Finch flashes back to The Machine's origin and how it was developed.

Going deeper into the mythos of the machine definitely seems to be the way to go.

Also at 9 PM: The CW has another episode of The Secret Circle, "Loner."

ADAM IS JEALOUS WHEN CASSIE BRINGS A DATE TO THE SCHOOL DANCE - A cute jock named Luke (guest star Zachary Abel) asks Cassie (Britt Robertson) to the school dance, and after watching Adam (Thomas Dekker) spend time with Diana (Shelley Hennig) at the boathouse, she accepts his offer. Meanwhile, Melissa (Jessica Parker Kennedy) sees the dance as an opportunity to get closer to Nick (Louis Hunter). Faye (Phoebe Jane Tonkin), on the other hand, has no plans to go and remains focused on finding a way to control her powers. Dawn (Natasha Henstridge) discovers someone from their past, an intense man named Zachary (guest star Dave Baez), is in town asking questions about the Cassie and the Circle, so she asks Charles (Gale Harold) to keep an eye on him.

For those of us who miss The Gates, note that this episode is written by The Gates creator Richard Hatem.

At 8 PM, CBS has another episode of A Gifted Man, in which yet again the guy's dead wife helps him be a better person. How are they going to make this last more than a few episodes? Your first clue comes from the synopsis for "In Case of All Hell Breaking Loose":

MICHAEL FACES A DILEMMA WHEN HE TREATS A PREGNANT PERSONAL FRIEND WITH A BRAIN TUMOR AND A LITTLE BOY AT THE CLINIC WITH SICKLE CELL. Michael works double duty trying to save a pregnant personal friend he recently diagnosed with a brain tumor and a little boy with sickle cell disease.

Also at 8 PM, there's a new episode of Star Wars: The Clone Wars, "Shadow Warrior":

The peace that settled on Naboo following the defeat of the Trade Federation blockade is shattered as Separatist forces again threaten Padmé Amidala's homeworld. This time, though, the invaders are led by none other than military mastermind, General Grievous. Anakin Skywalker, meanwhile, fights a long-awaited, epic battle against the renegade Count Dooku. The situation worsens as an injury forces Gungan leader Boss Lyonie out of action, and an uncanny look-alike takes over. Can he sway his people from rising up against their traditional enemy, the Naboo, and convince them to battle the real threat of the Separatists?

And check out a brand new clip, featuring a kick-ass lightsaber battle!

Meanwhile at 8, The CW has more of its spy-fi series Nikita, "Falling Ash."

DEVON SAWA RETURNS AS OWEN - While investigating an old corrupt Division program, P9, that seems to have resurfaced, Nikita (Maggie Q) and Michael (Shane West) run into Owen (guest star Devon Sawa). He tells them he is searching for Dr. Joseph Mars (guest star John Ralston), who is not only the mastermind behind P9, but also invented the Regimen and could help Owen wean himself off the dangerous drug. Michael is hesitant to trust Owen again but Nikita decides the three should join forces. Percy (Xander Berkeley) demands to see Alex (Lyndsy Fonseca).

But if none of those options appeal to you, Disney Channel has a brand new Wizards of Waverly Place, "My Two Harpers."

Since Alex broke up with Mason, she has been a constant third wheel to Harper and Zeke, until they gently hint their preference to spend more time together without her. Not wanting to spend time alone, Alex uses magic to create a Harper clone to hang out with. Meanwhile, Max comes up with an idea to open a Waverly Sub Station in the wizard world.

That's followed by a brand new A.N.T. Farm at 8:30.

But more importantly, at 9 PM, Fox has another episode of Fringe, "One Night in October."

As the victims of a highly intelligent serial killer "Over There" stack up, the Fringe Division "Over Here" is asked to assist.

Here's a sneak peek.

Also at 9 PM, there's another new Supernatural on The CW, "Hello Cruel World."

The broken wall in Sam's (Jared Padalecki) head causes him to have hallucinations, and he has difficulty discerning what's real and what's not. Bobby (Jim Beaver) worries that Dean is beginning to stumble under the weight of fighting Castiel and keeping an eye on Sam.
