I know there was a thread while back but couldn't find it.
I liked this show from the start and my take on the show is about that comic book. First time I saw it Walt was reading it his dad threw it in the fire and last night Hurley was reading it on the plane. That would kind of explain the monster polar bear we saw in the begining of the show. So this is my thought, the show is all about Hurley reading the book and there is never really a plane crash.
