I don't rewatch much. Maybe because my memory of movies is rather detailed, i dont know. The ones I've rewatched the most are...

The Thing 82
Alien
Se7en
Aliens
Psycho, original
Poltergeist
Jaws
Evil Dead 2
Godzilla vs the Smog Monster (Hedora)
Bram Stoker's Dracula, coppala

There's plenty of depth -- visual, sound and music craft, character development, story plot layers, and mood and emotion establishment in high degrees for these movies.

I watch some of my favorite horror movies as many times as a dozen or (quite possibly on some) more times in a single year. I do not know the exact number, but I will list 10 horror films, I watch a lot.

1. John Carpenter's The Thing (1982)
2. Jaws (1975)
3. Halloween (1978)
4. Psycho (1960)
5. Friday the 13th Part VII (1986)
6. Friday the 13th Part III (1982)
7. A Nightmare on Elm Street (1984)
8. Scream (1996)
9. Bram Stoker's Dracula (1992)
10. Predator (1987)

in no particular order

1: Scream
2: John Carpenters vampires
3: Silence of the Lambs
4: Tales from the Hood
5: Halloween 6: Curse of Michael Myers
6: Shaun of the Dead
7: The Shining
8: Dead Alive
9: Se7en
10: The Exorcist

I sorta have a predilection towards the 90's...
