don't watch in the name of the king unless you have a fastforward button. there are some genuinely funny horrible moments in it but the fight sequences are SO GODDAM LONG. I mean we LEFT despite laughing half the movie because we couldn't watch. there's also some really bad bollywood movies but you probably don't want to do that.
my friend jon has a massive collection of bad horror movies, but idk if you're interested in that. if you are I can just ask, but everyone knows the classics, manos the hand of the fate, plan 9 from outer space, leonard part 6, etc.
oh one movie he just DOES NOT SHUT UP ABOUT: Cabin Fever. he loves that movie. like it is his number 1 favorite SO BAD ITS BRILLIANT YOU MUST WATCH IT FOREVER movie.
also wicker man duh although I've heard you can watch the youtube clips. which reminds me actually!
