Well...I like it so far.
I'm glad I found this thread, I'm afraid to look anywhere else in case I run into spoilers...I knew a bit of stuff even before the show started over here (who dies, and so on). Some things I'd like to know: how many episodes are there? And are we always gonna be behind the US - they're about to get the second season, right?
As for the actual show itself, back when it had just started in America I read a theory on someone's LiveJournal about everyone on the island actually being dead, and the island was sort of...limbo. It's almost definately not true, but I love that idea...
