I haven't watched pretty much most of the MCU films. Only specific ones here and there. Ones that are pretty much standalone. Like the three Iron Men, Captain America films, both GotG films, I think I saw Avengers but don't remember anything. I also loved Black Panther. But I haven't watched the whole arc. I've been spoiled to most of it. I haven't even seen the MCU Spider-Man movies yet.
I literally didn't even see the third LotR film for over a decade. I didn't even know how it ended.
Joker. Don't really care. If anything it's been ruined by its fanbase, which is ironic as I still like Rick and Morty and Community despite their fanbases. (As for Community. I admit, I WAS their fanbase. But I was never a "freak out in a McDonalds because they ran out of sauce" Community fan. Just a Twitter campaigner. #SixSeasonsAndAMovie)
As well as most of the other DCEU stuff. I saw Bats + Supes in the theater just to watch a train wreck and that was the last thing. No Suicide Squad, no Justice League, no Aquaman.
Also, WestWorld, Bojack Horseman, nothing Anime because I don't give a shit, haven't even watched Black Mirror aside from Bandersnatch.
There's so much.
