Lars von Trier movies. He makes these movies that creep up on you and makes you feel bad. I think he hates people and wants to torment everyone. I watched "The House That Jack Built", there's a scene in that movie where the main character is very lucky, he meets a nice woman and takes her and her kids out on a date in the forest. And she is happy she met him and she is excited to go on the date. It could have been a very nice day. I never want to see that scene again, the psychological aspect of it is too rough. And von Trier is too good at making scenes like that, it's too well made. And that makes it truly horrible. Matt Dillon is very good in that movie, his acting, that makes it worse. And "Melancolia", don't want to watch that again either. Or "Antichrist".
And as Metalhead said, "Requiem for a Dream". Not watching that again. It's well made but after watching movies like that I just feel bad and want to get away from it.
