Blind Buy, which is better?

[rangers85]

I'm trying to decide on Amazon which would be the better blind buy as my 3rd movie in the B2G1. I'm deciding between Blood Diamond and The Fountain.

I've heard Fountain is one of those love em or hate em, but would it be kind of like Donnie Darko (which I loved) in that it doesn't quite resolve everything and is a kind of thought provoking movie that the American public as a whole seem to hate. I don't really have a certain taste in movies, tend more toward comedies, thought provokers, or just interesting story lines.
