ABC's remake of the alien invasion saga V is returning with more episodes -- and more ships! That's right, the Visitors are no longer just visiting, they're taking over. But aliens have been ruling our televisions for decades, so are we really that surprised? As a gesture of good will to our new alien overlords, here are some of our favorite alien visitors on TV, extra-terrestrials who once lived peacefully among us, but now permanently reside in our hearts.

In his first year on the air, Jimmy Fallon has unsuccessfully tried to reunite the cast of Saved By the Bell, settling instead for some great appearances by its former stars - albeit individually. However, much to his credit, he did manage to get the entire original cast of California Dreams to be on his show this week and sing their catchy theme song. Since some of those SBtB divas are still holding out, here are some other cheesy nostalgic teen shows from the '90s that we'd like to see get back together on Jimmy's show.

Considering the new HBO Friday night line-up (with The Ricky Gervais Show and Life & Times of Tim), Fox's Sunday Night "Animation Domination," and Adult Swim, I think it's safe to say that Americans have embraced cartoons for adults. We no longer believe that animation is strictly for children; instead, we give animated series a fighting chance, and openly enjoy comedy that isn't live-action. I'd like to think that if The Critic was created today, it would have been a hit, as opposed to the flop it was back in the mid-'90s.

Jim and Pam are having a baby this week on The Office and, unfortunately that's been one of those TV conventions that tends to send shows on a downward spiral. The Office has already barely survived the marriage of two leads (another frequent show killer), so to now add a baby to the mix is just asking for shark-jumping trouble. While a drama like Friday Night Lights, which is built around familial struggles, or a series like Friends, where characters mostly forget about their kids, can sustain their quality levels postpartum, plenty of other programs haven't fared as well after the stork dropped off its little bundle (or two) of joy. Here's a look back at some of the unwelcome arrivals that put a damper on once-successful shows.

What is with the TV industry's obsession with making shows out of movies released decades ago? And why make a new show from a movie that was already turned into a halfway decent TV series 20 years ago? Did the producers of the new Parenthood not witness the debacle that was Eastwick? (Apparently not.) Sure, some films have made a positive transition to television (M*A*S*H, Stargate, Friday Night Lights and Buffy the Vampire Slayer, to name a few) but for every success story, there's a massive stinker that sucks the life out of the source material and dampens our fond memories of the cinematic original. While Parenthood might succeed (given its awesome cast), we're at least hoping that it doesn't follow the footsteps of these complete duds.

Televised sporting events are already a pretty big deal for most people, but when you factor in the event status of the Olympics or the Super Bowl or the World Series, they become juggernauts. So why is it that fictional TV shows about sports are so much less popular? The high school football drama Friday Night Lights is one of the best shows on TV, but ratings are only so-so, and it was moved from NBC to DirecTV in 2008 (it will return to NBC in April). Luckily, other sports shows are still plugging along: My Boys, about a female sportswriter, will get a fourth season this summer on TBS, and fantasy-football comedy The League will get a second on FX. And, encouragingly, new shows are still getting made: Spike recently launched college football comedy Blue Mountain State and is prepping Players, about the owners of a sports bar. But historically, sports shows tend to hover in a sparingly viewed grey zone between regular TV shows and actual sports. Here are some of the best shows about sports that have ever aired, and don't be surprised if you haven't heard of some them.

When we heard that Melissa Joan Hart and Joey Lawrence were getting their own sitcom, we thought of a few '90s family comedy stars who are even less deserving of their own shows, due to their ultra-campy acting and unforgettable awkwardness. So while we may have appreciated some of these folks back in the day, we're in no rush to see any of them again in starring TV roles soon.

News hit yesterday of The CW picking up a pilot for a reboot of the late '90s classic Le Femme Nikita. Somewhere, thousands of 30-somethings grasped their burning arms, revealing a darkening tattoo of Peta Wilson donning a pair of stylish sunglasses, because let's face it: Nikita had one hell of a cult following.

There's something about the new Fox series Human Target that makes us feel like kids again. Why does this man-of-action adventure drama, starring Mark Valley as more-than-a-bodyguard Christopher Chance, suddenly take us back to the 1980s? Could it be that the show reminds us of a bunch of adventure series that were on the air back then? The first Human Target TV show failed back in 1992 because it had missed the 1980s action-adventure boat, but maybe now nostalgia-seeking TV viewers will give it a "chance" (sorry). We compared the new Human Target to some of our favorite '80s action shows and found that they had a lot in common -- although Target still has some tricks it can learn from them.
