Speaking of Lost - my friend Mike thought I was talking about it here; last week's episode really was interesting. I don't think that the entire show is inside Hurley's head, but - they certainly set it up so that it could be seen that way.
So what is going on? I have no idea. My wife and I tossed around the idea that everyone on the island had committed suicide, so they were all in purgatory. We were able to come up with reasons (based on the flashbacks) why most of the characters would be depressed enough for that; there are a few exceptions (Sun? Then again, she could be a murder-suicide with her husband).
Of course, that doesn't answer what the numbers are about, or a few other things. What about the kids who "the others" stole? Is that because they don't belong in purgatory? Then again, if the plane crash didn't really happen, then why would the kids have been there in the first place? There's also the whole "psyche experiment" feel to a lot of the stuff in the hatch.
When they finaly end this, it wouldn't surprise me a bit to see a St. Elsewhere style ending.
