What horror movie has the best special effects make-up?

Question by Sunshine: What horror movie has the best special effects make-up?
I love horror movies, am quite interested in the special effects make-up, and looking for some inspiration. What are some movies that have great make-up in them?
I am already aware of movies such as the Exorcist, so don’t bother mentioning them. It can be just creepy make-up, but I am looking more towards gore.

Thank you!

Day of the Dead (the one that takes place in the underground bunker)
Hellraiser 2 (the scene where the guy is covered in maggots is amazing.)
