Flash Forward had potential, but I didn't like what they did with the show. It had that weird cause-and-effect problem that plagues time-travel movies. Because someone saw something, he made it happen. I mean, it doesn't quite rape time-space like Doctor Who, but it also was trying to take the concept seriously, which usually makes it fall flat.
I was disappointed that they never addressed life insurance. People were free to cancel their policy for 6 months. Anyone who didn't (or suddenly applied) likely were dead in the next 6 months. The financial ramifications of that would have been interesting, but I guess it's not as exciting as exploding a toy factory.
I thought the first season of Heroes was phenomenal. It really delved into how people react to these newfound powers. Subsequent seasons weren't as good, but I still enjoyed/tolerated them. Surprisingly enough, I found myself more interested in the carnival. That villain was powerful in a Magneto sense. But I think that they tried too hard to jack around with the mythology and history of the series. I understand the writers' strike had something to do with that. And the problem with going beyond the first season is that they had to impose false limits on the uber characters. At least season 1 had some workable limits. Peter didn't know what the hell he was doing, Hiro had his self-imposed code of honor, and Sylar…well, he didn't have limits, but that would be okay as a growing juggernaut who is stopped before he gets too big; he shouldn't have been allowed to live past the first season.
Arrested Development is certainly worth watching, and there's a new season being made, so you can prepare for that.
I've finally gotten into watching the new Doctor Who (had some weird mental block where I couldn't bring myself to watch new seasons without seeing the old seasons but I finally got over that shortcoming). Since it seemed like I was the only geek who didn't watch Who, you probably already know about it, but if you also never saw the series, I can definitely suggest it. BBC America is showing several episodes a week, but they're not entirely in order (or even within the same series). You could rent or buy the series.
Spring Break. I miss the days when that was a meaningful phrase.
