it's hard to pick, but i really like Possessor (2020), it's a cool dystopian science fiction horror-ish movie that scratches a lot of my itches
i also rate some of the Andy Kaufman movies really high, like Synechdoche, New York (2008) and Eternal Sunshine of the Spotless Mind (2004)
most of my favourite movies are just mindfucks about identity or memory, because that's the flavour of my mental illnesses, lol
