Until the Very Last Line

The only way I can describe this movie is by saying that it's like one of those Dan Chaon stories from "Stay Awake" where, until the very last line, you have no idea what the story is about. 

In this case, maybe by the end of the credits.... 

It's a very subtle film. I liked it because I have this tendency of being able to figure out what a movie is about before it starts, but this one really demanded a lot of patience, not just in some single plot line that you didn't expect, but really in the totality of the the whole thing you didn't know what it was about until maybe after it was over.
