I can't make an order so just do with my list as you want
Psycho
Alien
Silence Of The Lambs
The Shining
The Texas Chainsaw Masacre
Nightmare On Elm Street
Jaws
Poltergeist
Halloween
Friday The 13th
The 1st Scream
The Devils Rejects
It
The Evil Dead
and that one with all the chick cave divers in it
I know some of these might be considered thrillers so sue me
I didn't see this before.
I forgot about Jaws

I would def. knock off exorcism of emily rose in order to put Jaws on there.
The Devils rejects and House of 1000 corpses where some nasty movies, I don't really like Rob Zombie movies like when I watched the new Halloweens I wanted to kill myself.
when you say cave jumpers do you mean The Descent?
