They did something like that last year didn't they? I don't watch it and I watched that episode and really thought the show was interesting. I love JJ Abrams. I used to love Alias.
My problem with all of these shows is I typically don't watch tv so I never recall what network and time things are on. That is why iTunes was so wonderful for me. I used to watch Alias and 24 regularly and then they put them on opposite each other. Then I liked the Gina Davis the Amereican President show. Typically the show I love the most ends up being preempted for various reasons and/or loses its audience when the network moves it.
