9. Suspiria

Suspiria is one of those movies that separates casual horror fans from diehards.

10. Session 9

If you can figure out the twist in this movie before it happens, you’re way smarter than most people. The ending aside, the whole movie is brilliant in how creepy it manages to be. Even after it’s all over and the lights are on, Session 9 will linger in your head for a long time.

11. Shaun of the Dead

It takes smart writing to make a movie about dumb characters seem intelligent. Shaun of the Dead pokes fun at all the overdone tropes in the horror genre. We also get a glimpse of a truth often avoided by zombie films—even after the zombie apocalypse our dumb human relationship drama goes on.

12. Funny Games

This is one American remake that is really decent and stays close to the original. Funny Games is about the sheer terror of a pair of killers without any motive at all.

13. Saw

Say what you will about the never ending Saw franchise, the first one was just so original. We hadn’t seen anything like this before.

14. The Vanishing (1988)

You absolutely cannot watch the American remake before you have seen the original The Vanishing, even though Sandra Bullock and Kiefer Sutherland are in the remake. The original is universally revered among smart horror fans for being one of the most intense and unsettling movies of all time.

15. The Others

A common theme among the “smart” horror movies is they play with epistemology—what is reality? Do we know “what’s real”? Are the lives of the Stewart family real, or those of The Others?

16. American Psycho

Bret Easton Ellis is such an insanely good writer and this story is awesomely messed up. If you haven’t read the book, I strongly urge you to do so, even if you’ve already seen the film.

17. Scream

The Scream series is consistently underrated for being a cliche horror movie series when the reality is it’s a horror movie series about cliche horror movie series. It’s meta.
