Beau is Afraid was the last one I recall. I think it was mostly the latter half of the movie where I started to get a bit confused and needed the ending explained to me.
What movies made you look up some kind of explanation afterwards? I feel like I have done it several times in the past for more surreal movies but can’t think of any other examples.
It can also be a TV show.
Of these, I think mother!. The Images and vibes there are taking up the most rent-free space in my brain.
I neglected to mention Gasper Noe; basically everything he’s done. But his work leans too hard into palpable horrors for me to ever actively recommend.
