For animated sci-fi, I'd go with A Scanner Darkly. It is about a future LA deep in a drug war that uses rotoscoping to lean into the feeling that not everything is right.

Deathgasm. It's about a bunch of metalheads that find some sort of old hymn. When played, it summons hoards of demons/zombies. So then they start fucking up the zombies. I vaguely remember one of them being impaled with a dildo? Either way, it was an entertaining "turning your brain off" watch that's pretty unknown afaik.

For comedies: Waiting for Guffman American Movie

For sci fi: Beyond the Infinite Two Minutes (admittedly, foreign so you have to be cool with subtitles.)

Creep (2014) and it’s sequel are some of the best horror movies I’ve seen from the last decade (not saying much, considering the genre is filled with stinkers, but still). They’re both presented as documentaries, and the characters are a little more believable than your average horror character.

I actually prefer Creep 2 over the first one. The protagonist in the first movie is compassionate to a fault and he makes some really dumb decisions. The protagonist in the second movie doesn’t take the threat seriously at the start, but once she realizes the danger she actually gets her shit together

The antagonist in both movies is a brilliant character, and you see some great acting on his part. The guy is an absolute mental case but endearing at the same time. His behavior is both deeply disturbing and hilarious
