So, it goes like this. A guy walks for a long time, then talks to someone for half an hour. You think it's important and try to follow, but the acting is too level all the way and the dialogue overly pretentious so it gets too boring and you go the toilet or have some tea. When you return, the characters are still talking, but it doesn't look like you've missed much. When the scene is finally over you find out that the director just dropped this plot line as it leads to nowhere, and it's okay you didn't see half of it. Then the main character walks again for a long time, finally finds someone else to talk to and the story repeats. They talk, then the subject is dropped completely and the guy he talked to never appears again. Then he walks again... You get it. And after 3 hours the movie just ends.
