Closer directed by Mike Nichols
The opposite of a love movie, it takes a closer non-Disney land approach to four individuals and their relationships with each other. It also asks does loyalty to a person equal love. Can you love without the loyalty? If you don't want to see it because it deals with such open-ended questions, you should at least see it for Natalie Portman. She's truly exciting in the film.

P.s. Totally feel like I've written about this before. Time for me to update the labels.
