The Sarah Connor Chronicles has been picked up for a full second season.
Of course, this would be even better news if the show gave any signs of improving, but five episodes into the second season, the flaws that marred it in its first are still going strong: great acting, great character work, great individual scenes, but the plotting, in both individual episodes and the overarching save the world arc, is nonsensical. The next to last episode aired, "Alison from Palmdale," is a perfect example. Summer Glau is incredible as three different people in the same body who combine into whatever the hell Cameron is right now, but the notion that Cameron has enough empathy to become Alison--who understands and feels emotions, like fear, grief, and anger, which in the past have left Cameron baffled--is too much to swallow. We've already got one show about a genocidal war between dirty, sweaty humans and immaculate machines confused by these things we call 'feelings' in which the actual nature and capabilities of those machines have been kept too fuzzy for too long. We don't need another. Sarah Connor is still the most interesting and complex SF on TV right now, but that's mostly because of its parts, not its whole.
