I was talking in Global Chat, and someone was speaking about The Descent. Most definitely on my list of movies that I have watched. I have never watched The Ring but I heard it is one of the best...I can't include it on my personal list.
Here we go, DaGip's Top Ten Must Watch Horror Movies:
10. Killer Klowns From Outer Space
9. American Werewolf in London
8. The Howling
7. The Thing (1980's)
6. The Shining
5. The Blob (1980's)
4. Drag Me To Hell
3. The Descent
2. The Loved Ones
1. The Exorcist (duh!)
These are only the top ten in my experience. This list could change as I rethink things and remember movies that I have seen in the past. I suppose some of the real oldies (Dracula, Frankenstein, The Mummy...) we should watch out of nostalgia, but I never found them that scary or shocking. And the Conjuring didn't make the list, sorry.
