This show is great! The pilot immediately hooked me in, and I feel like it's on track to become my favorite new show of the season. (It helps that Danes and Lewis are both great in their roles! The two really shine when they're on TV.)
Also, has anyone else checked out homeland It's the show's interactive online site. Basically you beat the different levels of the game to reveal "secret files" about the characters on the show. I haven't gotten through the whole thing yet, but I think if you've seen the show it's definitely worthwhile.
