I watched a lot of 18-rated films from about age 8 onwards - stuff like Terminator, Total Recall, Predator, Robocop, Alien/Aliens, the Rambo movies... 80's/early 90's gory action stuff basically.
The only thing that really stuck with me is really random - the scene in "The Fly" where he armwrestles the guy in a bar and the guy's bone snaps and comes out the side of his arm. I was ****ing shook. Dunno what it is about broken bones - we watched "Frozen" ("trapped genre" horror with teenagers stuck on a ski lift, not Disney hijinx) and while I'm rarely bothered at all - I could not watch when the broken leg bone came out through the skin.
TBF I actually saw this happen to a kid on my street IRL when I was quite young when he was knocked off his bike by a car. Maybe that's it

. Scarred.
