It's an entertaining film. Better than most scary movies nowadays.
Good acting, good script, and the movie is not super predictable. I've watched this movie multiple times and I enjoy it each time.
Definitely adds to the movie if you have a home theater system or surround sound. There's so many crazy sounds in this movie.
The only reason I will not give it 5 stars is because there is one scene that just doesn't do it for me. A bunch of hands reaching is not scary especially when all those hands manage to not grab a single person.
Other than that, pretty entertaining film.
