Count me in as another Alias fan! I'm currently in the process of re-watching on DVD again, at the moment about a third of the way through Season 3. I too loved the way Season 1 episodes in particular ended with a cliffhanger. Watching first-run on TV, that was quite aggravating having to wait a whole week to find out what happened next. On DVD, if you plan to watch only 1 episode, you may find yourself saying "okay, just one more" a few times before you finally call it a night!
