In all honesty, I have NEVER been scared of any movie growing up as a child to this day at 19 yrs old. My little sister said she wanted to watch it, so I bought tickets for her and I. Not thinking it was going to be that good. I was definitely wrong. This movie is the scariest movie I've ever seen. I highly recommend this movie to anyone and everyone. IF any other movie has scared you, this one will top it.
p.s Good luck going to sleep. I had a lot of trouble last night.
