My Top 4 are just the last four movies I rated five stars. My actual favourite movie of all time is Persona.

2017
The investigation in this movie is like watching someone investigate why an eighty-year-old chain smoker had a heart attack. That seems pretty fishy; we'd better go talk to literally every person he ever knew to unravel this mystery.
It's insulting to Vincent van Gogh to baselessly insinuate things about his life like this and it's insulting to the audience to expect us to even entertain this ridiculous murder conspiracy theory.
Mostly, this is just so boring, though. Oh my god, this movie is so damn boring.
