Jump scares in movies are pretty much the same as jump scares IRL.
Imagine I go into a room and hide behind a door only to jump out at Rym.
Sometimes it won’t work. Then I look like a doofus.
Even if it works and Rym jumps, 99% of the time he’ll just roll his eyes at me. It wasn’t funny. It wasn’t clever. Even if I think it’s funny, nobody else does. It certainly wasn’t scary. There really are not a lot of positive things to say about this behavior.
On that extremely rare occasion a jump scare is somehow appropriate. There’s some sort of reason to do it. You get the timing and positioning just right. Everyone recognizes how good it was, including the victim.
The only good jump scare in a movie I can think of is in Alien when you think it’s an alien, but it’s actually Jonesy the cat.
