Possession

Some things in life are inherently gruesome: birth, murder, etc. This movie makes physical - makes visible - the internal gore, the mental anguish, the torture of heartbreak.

It's incredibly uncomfortable and confusing to watch, like the experience it depicts. That's why this movie is so good. Everything falls apart and pieces are grotesquely reassembled like the patterns of divorce.

The script is incoherent at times but littered with gut-punching accuracy:

I can't exist by myself because I'm afraid of myself, because I'm the maker of my own evil.

Nobody taught me that. That's why I'm with you. Because you say "I" for me.

I met a man who loved everything, and he died in a flood of shit.

You know what this is for? All the lies! [slaps]
Then you would have to add more.

That scene had me shuddering. The whole thing had me shuddering.
