Twenty minutes in and I'm already scared

I sent a text to my mom this evening telling her that I was watching her favorite movie of all time and she responded with "Ewww. Why would you do that? You're going to have nightmares tonight." She's so right. It hasn't even been an hour into the movie and I'm already scared shitless by this movie.
The original version starts off slower and has less gore, but I like it much better than the remake. Who likes remakes of anything anyway?
