What Horror Films Do You Like to Watch Again Around Halloween?

[fabito]

I love horror movies and there are always ones I want to watch on TV around Halloween. TCM features horror films the whole month of October too. But I have a few that I could watch again and again like:
Alien
Aliens
The Host
Train to Busan
Found-footage style:
The Blair Witch Project
Quarantine
Paranormal Activity
Jeruzalem (badly reviewed, but I don't agree)
I'm always looking for great horror films. Please post your favourites.
