Chuck I watch, 24 I don't like, but that "Alias" thing intrigued me! And season 1 is on DVD very cheap.
I've read a bit on Wikipedia, though I'm a bit scared of spoilers. Can you say something more, what kind of TV show is that, I mean is there one plot, or each episode is one mission? If yes, could you give an example?
And most important, did they manage to close all the threards before ending the show, or it's one of these where they just screwed the viewer?
