Rosemary's Baby changed my life in the worst ways

I can't at people finding Insidious scary

those are really good choices as well

but did i lie

Neither can I. I just saw it as a really good comedy movie.

I typically find horror movies to be hilarious. But, if I had to choose, the Jeepers Creepers series is definitely creepy. But I still laugh my ass off at it whenever I sit down to watch it.

All of these are horrible, horrible choices. I don't get scared easily and I don't think there is a movie that has scared me, but I will recommend IT, The Shining, Triangle, The Strangers (very, very good), Trick 'r Treat (more camp than scary, but good), To Sir With Love, Audition (do NOT research it online or you will ruin the movie for yourself), Oldboy, etc.

This. One of the biggest let downs ever after hearing how terrifying it was from everyone and their mother

In my theater, it was so scary that a lot of people left during the film.

I hardly get scared, but I felt like the original Saw was psychologically scary.

This film was terrifying.

Part of Me 3D

I'm JKing I actually really loved it

NOOOOO

To Sir With Love? Maybe I'm thinking of the wrong movie..

Yes one of my favorites that still semi freaks me out

Also the first half of the remake of The Hills Have Eyes legitimately scares me still to this day

The Fourth Kind
Insidious
