I thought the movie was crap, for what it's worth.
I felt the same way about it as I did "Blindness", that is, if you have to box your characters into an incredibly artificial situation to get the behavior you want, it's possible that your novel doesn't say as much about "human nature" as you seem to think it does. But that's my two cents, and the book is on my reading list. I'll give it another go.
Topic? There was a topic around here?
