What's the worst movie you've ever seen?

This one is going to be a bit esoteric because it's a very "local" movie but I'm gonna try my best to explain.

I've been recommended countless time by the gen X of a movie called "Le Père Noël est une Ordure" (Santa Claus is a Bastard) which is a 80's comedy that ticks all the boxes for garbage conservative humour except for some reason everyone above their 40's seem to think it's really really funny.

It's deeply misogynistic with extreme domestic abuse used as a plot device and running gag, as well as general contempt for women. It's outright mocking poor people, shows disdain for white collar workers, while poking fun very respectfully at the bourgeoisie. The richer the less degrading. I'm pretty sure it has some racism but I don't care to remember. And the most egregious of all is how massively transphobic the movie is. There's a trans woman character, she's an asshole, she's creepy, and being trans is mostly what's expected to be the actual joke.

I'm not even sure it has genuine comedy at some point, the cringe makes it hard to remember anything
