I didn't want to get sucked into this show, but it's pretty good and I find myself getting caught up in it. The characters are interesting (except for Ali Larter's single Mom), and the story is pretty cool and well-written. The Japanese guy completely runs away with the show, and I admire them for having the guts to run all of his segments entirely in Japanese with subtitles.
The thing that got me really hooked, though, were the endings. I missed the first episode and only saw portions of the second, but then at the end we watched a huge nuclear explosion destroy New York, and we learned (thanks to some time travel shenanigans) that they have three or four weeks to stop it. Very unexpected, very ambitious, and very cool. The third episode ending was possibly even better, as the cheerleader with super Wolverine regeneration powers was assumed dead, and woke up during her own open-chest autopsy. The show has guts, I'll give them that. I'm very interested to see where it goes.
