People are voting emotionally.

I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.

I wanted to like it more than I actually did... But much of the humor totally escaped me and I walked out only mildly impressed.

While it doesn't offer any answers, it both thrills and makes you think.
