The Outsider

Just because a movie has a snails pace, does not mean it can not be brutal and violent in spades. We got one of those cases right here. It's about honor and loyalty. A major part of the movie is in Japanese (with subtitles of course), but our main character is an english speaking one. Which is the old "stranger comes into town" kind of thing.

In this case his invasion into this culture that most westerners may not be that aware of, is really the driving force. He does learn fast, but he is also human, so he does have some urges and he has feelings too (even if sometimes you may think otherwise). Brutal, honest and without really taking compromises, this may feel too long for some, but will be a masterpiece for others.
