Aliens will destroy the world if America's first black president and Alaska's iron lady can't agreeS

Aliens have it in for us on television this week. They're attacking on The Event, they're firing up reactors on V, they're facing off on Stargate Universe...and they're invading Los Angeles. Yes, there's a Battle of Los Angeles TV movie.

Plus Walter may finally be going off the deep end on Fringe, Anakin is taking no prisoners on Star Wars, and Superboy's lost his memory on Young Justice. Plus Firefly is coming back in style! Television is your friend this week.

Today:

The Event returns! Tonight sees a two-hour special presentation of the midseason premiere of this struggling show. And early buzz suggests tonight's two-parter is when the show really hits its stride. And in an effort to be more relevant, an Alaskan woman politician is going to be pitted against our black president. Here's the blurb:

President Martinez (Blair Underwood) and his longtime Chief of Staff (guest star Roger Bart, "Desperate Housewives") charge the intelligence community with decrypting Thomas's (Clifton Collins, Jr.) satellite message, but more importantly determining to whom it was sent. While they are distracted, Thomas unveils a surprise attack, but he does not anticipate a heroic stand-off with Blake Sterling (Zeljko Ivanek), who learns an important lesson about Sleepers from Maya (guest star Clea DuVall, "Conviction"). Meanwhile, newly appointed Alaskan Senator Catherine Lewis (guest star Virginia Madsen, "Sideways") threatens to divulge information about the Mt. Inostranka detention facility on an episode of "HARDBALL with Chris Matthews" (playing himself). Elsewhere, Sean (Jason Ritter) and Leila (Sarah Roemer) get a fresh lead on the whereabouts of Samantha, but it leads them to a dramatic turn in their lives. James Dempsey (guest star Hal Holbrook, "Water for Elephants") foresees that he and Sean will once again cross paths.

And here's a clip.

There's also a new episode of the quasi-sciencey House on Fox at 8 PM, "Bombshells."

Also at 8, there's a new Adventure Time with Finn and Jake on Cartoon Network. That's followed by Mad at 8:15, and a new Regular Show at 8:30.

And then there's World's Weirdest, a new show on National Geographic that is airing its first three episodes back-to-back from 8 PM to 11 PM: "Freaks in the Ocean," "Freaks on Land" and "Freaks in the Sky."

At 9 PM, there's Syfy's remake of the British show Being Human, "Children Shouldn't Play With Undead Things." In which Aidan and Sally try to prep Josh for a hot date... Watch the clip.

Stargate Universe is back at 10 PM on Syfy. And looks like the team is having a wee spot of bother with the Destiny.


Tuesday:

Syfy is having a Star Trek: The Next Generation marathon all day.

No Ordinary Family is off for a couple of weeks.

But there's the penultimate episode of V season two, at 9 PM on ABC, "Devil in a Blue Dress." Here's the blurb:

Anna is about to pull the switch on the planet's first Blue Energy reactor, but Sid realizes that the size of the reactor is much too large for just the various Concordia sites - the Fifth Column needs to figure out what Anna is really up to. And Diana tells Lisa she must act against Anna now, fulfill her destiny and save humans from annihilation.

And here's a whopping 10 minutes of sneak peeks.


Wednesday:

Today's Syfy marathon: Star Trek: Enterprise.

Sym-Bionic Titan returns to Cartoon Network with a new episode, "Escape From Galaluna," at 7 PM, in which the gang recalls their departure from, you guessed it... Galaluna.

At 11 PM, SOAPNet has another episode of Being Erica, "Jenny from the Block."


Thursday:

Syfy is back to marathoning Star Trek: The Next Generation. Plus Syfy has started showing the 1980s movies a lot in the evenings, in a weird order. Like Star Trek III followed by Star Trek II, or Star Trek II followed by Generations.

At 8 PM, there's a new Big Bang Theory, "The Prestidigitation Approximation."

Leonard must choose between new girlfriend Priya and his friendship with Penny. Meanwhile, Howard drives Sheldon crazy with a magic trick.

At 10 PM, there's another episode of the superspy parody Archer, on FX, "Movie Star":

The normal childish squabbles, sneaky backbiting, and petty jealousies at ISIS are multiplied exponentially when a famous Hollywood actress, Rona Thorne, spends a week shadowing the agents as research for an upcoming role in a spy movie. A movie in which Malory would – and may – literally kill to land a part.


Friday:

There's no new Smallville or Supernatural. But the Cartoon Network has you covered.

It all starts at 7:00 PM with Young Justice, "Bereft."

Young Justice discovers that they have forgotten the last six months of their lives, including each other and a final fateful mission in Bialya. The team turns to Miss Martian to recover their memories, before it is too late for Superboy.

That's followed by Ben 10: Ultimate Alien at 7:30 PM ("Girl Trouble"), and then Generator Rex at 8:00 PM. ("Robobobo".)

At 8:30, there's a new Star Wars: The Clone Wars, "Citadel Rescue." It's the conclusion of the big three-part story arc, and it looks like some pretty heavy stuff will go down.

And then there's an Earths-shattering new Fringe at 9 PM, "Os.":

The Fringe Team investigates a group of thieves who can break the laws of gravity. Meanwhile, Walter attempts to delay the damage he's caused to the fabric of the universe.

And here's a clip, featuring a Parliament-Funkadelic shout-out.

There's also a new Onion News Network on IFC at 10 PM.


Saturday:

With Battle: Los Angeles coming out in theaters on Friday, some of you may be left hungry for an extra helping of alien mayhem in the City of Angels. So Syfy has your back — there's a Syfy original movie called Battle of Los Angeles airing tonight at 9 PM. No, there's no chance of confusion here. This is from The Asylum, the same lovely folks who brought you Transmorphers, Almighty Thor, Alien Vs. Hunter, and many, many other "I can't believe it's not a big-budget Hollywood blockbuster" films. Here's the blurb:

Hundreds of extra-terrestrial ships swarm Los Angeles, causing death and chaos ahead of an impending alien invasion. A small group of United States military personnel are able to get underground, where they learn the only way to stop the invasion is by destroying the mothership from within. It falls to two determined soldiers to finish the job before the human race is demolished. Stars Nia Peeples (Pretty Little Liars) and Kel Mitchell (Kenan & Kel.)

And there's a splodey photo from the film at the top of the page.

At 9 PM, BBC America has the original British version of Being Human, with "The Pack."


Sunday:

Fox's animation bloc is here for you once again, with The Simpsons at 8 PM, Bob's Burgers at 8:30, Family Guy at 9, and Cleveland Show at 9:30.

We meant to mention this last week, but the Science Channel has started re-showing all the original episodes of Joss Whedon's Firefly on Sunday evenings, with special segments in which science fiction physicist Michio Kaku speculates about the scientific plausibility of Whedon's world-building. Tonight, there's "The Train Job" at 9 PM and "Bushwhacked" at 10 PM.
