IMDB

A group of teenage schoolgirls go to spend their summer vacation with one girl's aunt after losing their go-to house. Unfortunately, this house is haunted or the girl's aunt is a demon--I'm not wholly sure. Most of the girls have names that indicate a superpower or defining characteristic (Kung Fu, Gorgeous, Melody). Basically the house comes to life and eats or kills them.
Now this is a fucked up movie. It is hard to even really explain what makes this movie great. There are painted cutouts of the sky and trees in the middle of the forest that the girls stand in front of. A piano eats a girl. A head flies around and bits a girl on the ass. It is just insanity and I loved it.
This is a crazy movie that would be great to watch with a group of people. I watched it by myself, late at night. Basically, nobody will watch crazy movies with me. Very recommended.
