Titane. If I had been told beforehand that a woman being fucked by a car would be the least messed up part of the movie, I'm not sure I'd have believed it; however, that movie has burned it's way into my head like few others have.

Machine Girl and Tokyo Gore Police did it to me in a good way.

The Eric Andre Show

Monster musume

Just watched Beau is Affraid. Good movie but holy shit is it ever weird.

Possession. That movie is a ride.

Butterfly Effect

Belladonna of Sadness and maybe Angel's Egg.

I've seen weirder obscure experimental non-anime films I've forgotten the titles of. If I remember, I'll add it here.

Splice

2001 A Space Odyssey

Centaurworld and Doom Patrol, but both in the best way possible.

Gozu

Wounds.

Sci-Fi horror is my jam so I’ve definitely seen some weird shit but that was just wtf. Notable mention for splice.

Inherent Vice

A Serbian Film.

That one is beyond fucked.

Nip/Tuck. Like every episode.

Beef. What a ride.

The Taste of Tea. Japanese stuff can be pretty weird, but I had absolutely no idea what that film was about.

The House on Netflix. I watched it last Christmas and I'm still not sure what I think about it.

The Northman. At no point did I know where that film was going, and when it was done I just sat in my theater seat for a second bewildered at what I had just sat through.
