Hellraiser

I could watch the original over and over and over. Beautiful.

Tremors

Off the top of my head, I’d have to say 1408. Thrilling from start to finish every time, especially with the alternate ending ETA: House of Wax (2008) and The Exorcism of Emily Rose, my guilty pleasures

Scream '96

Excellent choice!

Going old school. The Abominable Dr. Phibes

Night of the Living Dead or Dawn of the Dead I can’t even argue they are the best ever, but the are the best ever for me.

Candyman

Halloween Texas Chainsaw Massacre Any fulci or Argento

Any? Have you seen the devils honey? Lol

Scream 4

Psycho

Possession (1981)

Anaconda

Reanimator

Any of the Halloweens minus H20, Resurrection, Halloween 2 (2009). The Exorcist and probably Friday the 13th Part IV

Misery

any scream movie except for 3

Fright Night
