It’s, uh… it’s interesting. I wouldn’t call it a good movie exactly, but it’s not terrible either – very campy, very weird, often funny without meaning to be, and clearly a product of the 70’s, but it’s a fun and ridiculous watch.
Lots of people say it’s incomprehensible because they just focus on the weird shit (of which there is plenty), but it’s a pretty standard “dystopian future where the elite live lives of plenty by subjugating masses who live in squalor” trope at its core. Like Elysium but made by hippies
