i think it's not really the movie genre that you wanted. but it's a nice japanese movie. It's not gore something, psychological stuff. it just that it's all F word up movie. you'll ask yourselves: "Wtf did I just watched?"
Anything from David Lynch, for sure. Specially Eraserhead. Oh, and "The 120 Days of Sodom". Definitely not recommended for children or sensible people. I almost couldn't watch it to the end.
The Enemy.. I really don't get the plot and especially the ending..although I initially understand the beginning, still my pensiveness really didn't help out to figure the story of this film..
