I don’t see any recommendations for The Lost Boys yet. It’s super '80s in the “both Coreys” way. It’s dated, but still a lot of fun.
Prince of Darkness is a guilty pleasure for me. I love religious horror, so it’s my favorite John Carpenter movie. There are some fairly violent bits, but it’s not overly gory like a slasher flick. If you’re okay with The Thing, this one should be fine.
The Endless is also religious horror, but it’s more psychological. There’s not much violence, but it’s very tense.
Little Monsters (the 2019 one) is a heartwarming comedy about a teacher who has to protect her class from a zombie apocalypse during a field trip. It’s got a moderate amount of zombie-movie gore, but it’s treated in a humorous way. If you’re okay with Shaun of the Dead, it should be fine.
I theorize that the fragile straights aren’t actually straight. Which I assume is what the developer is poking fun at with the quotation marks.
Our social default is still to assume that most people are straight. It doesn’t make sense for a straight person to have a driving need to prove that they are straight … unless they think someone would have a good reason to put them into a “non-straight” category.
