What movie ending made you say "what the fuck?"

Im searching for movies that let you like thisat the end.

For me one of the movies that I was all the time thinking " what the fuck is happening" is a comedy movie called Night in the Woods.

Most horror movies....sorry but horror movies, the actors are so stupid. And they ALWAYS open the god dam closet, like haven't they seen a single horror movie??

Butterfly effect, Shutter Island, Donnie Darko, Inception, Fight Club, Get Out.
Here you go, mindfuck movies are the best.

Requiem for a dream
Mind fucked I mean like you know what happened but like tf.... who does that?

the mist. i liked the ending for being something different than the usual but it will still a huge shocker.

A serbian movie. The entire movie is weird as fuck but the last 20 minutes of the movie made me feel sick for the rest of the night.

If want you want to see something disguisting then serbian movie will do it, but it is a pretty shit movie overall.
Some decent mindfuck movies would be donnie darko or inception

Shutter island and inception were just like wow for me at the end.

Get Out , the shawshank redemption , bladerunner2049 & inception
really good movies

The Invitation is the type of movie you're looking for mate ~ begins pretty simple, it's a small reunion for friends and the end will brain fuck you, I suggest it. I've re-watched it like 4-5 times now, very addictive movie.
