I really enjoyed this movie. The subtleties of the actions of the characters is really what drives the story forward, moreso than the dialogue. There's a lot of times you'll have to read between the lines of scenes, and really get into the sub-context to completely grasp an understanding of what's going on. With that, it's not a movie for people who want things a little more fast paced, or completely spelt out.
This movie has an artistic feel with the lack of dialogue, some interesting ad-libbing, use of natural sound vs music to enforce feelings. I'm really on the fence about this movie. I was bored for periods of time but the interaction between the characters seemed so natural that it has moments of fascination for me. If you want a movie with lots of action, lots of emotions, or a neatly tied ending, I'm going to recommend you pass on this movie.
