What horror movies do you know that doesn't throw jumpscares at you every 5 minutes, but rather uses suspense and atmosphere to keep you at the edge of your seat?
I think it'd be really hard to mention horror films with NO jumpscares as it's just become par for the course. However, here are some which balance any use of jumpscares out with really good other elements:
while im sure theres some jumpscares in these, they are earned and do not rely on them:
the witch
the dark and the wicked
halloween (1978)
the lighthouse (debatebly horror)
but more seriously, there are some that are atmospherec horror with very little jump scares (if they are in the movie, they are all earned):
hereditary
the witch
the blair witch project (1999)
suspiria (2018)
the wailing
