What kind of scary? Blood and guts scary or ghosts and paranormal scary? If you want blood and guts then Id say; Saw, Cabin Fever, A Nightmare On Elm Street, Re-Animator, Hellraiser, Candyman.. any slasher film from the 80s really. As for the paranormal I would say to avoid most of the more recent stuff because its CGI crap. Watch something like; The Exorcist, Amityville Horror, Poltergeist, Rose Red or The Conjuring. If you want something more brutual go with an exploitation film like Martrys, Cannibal Holocaust, A Serbian Film, I spit on Your Grave..
Or check out some of the Asian horror films. Audition was brilliant.

I'd say "The Exorcist" is objectively the best scary movie I've seen, because there is actually a really good story at the heart of it, which is about a priest who has lost his faith -- and yet now must face the ultimate evil in order to save a little girl's life and redeem himself:
My personal favorite scary movie though is "1408" with John Cusack haha. It's not the scariest movie out there, but it's very good at being creepy and captures what it's like to be in a long, trippy nightmare:
