This movie is black and white and it has a different frame ratio. At first, i thought they were going to do it because they wanted it to look like an art film but if you ask me, from what i watched, i am certain that this was done because of artistic and also satiric reasons. This movie is a great drama and also is a great comedy. Directing is really unique. Movie doesn't treat it's audience like they are stupid people. Movie respects the audience. For example, instead of a broken elevator sign, you see the inside of the elevator and you see that it doesn't come. When the character goes in a dark room, actor isn't pretending to be in a dark room, it is not a low lighted room that you can see but actor can't, you also can't see anything and it feels real. When a character closes other's eyes, before you see that, also your view is blocked by hands on the camera, which is your eyes. You feel like you are inside the film and it is amazingly done. When they listen to the song that should be amazing you hear nothing at all because they want you to imagine it since it will be different for everyone. And there is a scene in the school that it is really really funny and intelligently done. I won't spoil but i was laughing way too much at it. Movie tells a few different stories, panic attack, love, friendship, revolution and a whole other themes that are followed by their own scenes. Every thing in the movie leads somewhere and in every ending, it remind us that the world is cruel.Movie is funny, dramatic and exciting and overall it is very good. It makes fun of the Mexican so called art movies and also that maybe the cause of the black and white colour of the film. And it succeeds to be satiric in a good way. I am giving this 8/10 because i felt like it dragged a little on the last act. But, nonetheless i found it to be very intelligent.
