Mooseboy: The fact that they end it with "Oh, they're dead" really ruined it for me. Maybe its just because I don't believe in the afterlife or anything, but I found their time at the Dharma initiative was much more explantory, and everything after that kind of went down hill. The temple and all the other spiritual stuff? Meh, give me more sci-fi.
I don't think it was so much "Oh, they're dead" as "Oh, they eventually died" which goes without saying really.
I didn't mind it. It was always going to be a bit disappointing, but it was OK.
