I agree with Eraserhead. I thought it was horrendous, pretentious, boring and all in all, meaningless.
Martyrs was a terrifying film. It is a group of old people who think that by torturing young girls they may cause on them to have visions to prove once and for all if there is something after we die.
Then, there was another French film - god, they make strange films in that country -, which I can't remember the title right now. It was a personal project of the director, who had self-mutilated when she was younger. So it is about a wealthy professional woman who hurts herself by accident, but she only realises that she has bled a lot when she arrives back home and undresses to go to bed. She doesn't understand why she didn't feel any pain at all. So she begins to obsess about her lack of feelings towards pain and she hurts herself in increasingly disturbing ways. She never leaves her home now, and ends up losing her fiancé, her buoyant career, the contact with her family and friends. She feels attached to nothing, and ends up cooking and eating her own flesh. This film was obsessive and weird,and extremely difficult to watch for me, but I thought it was an excellent film.
