Finally a movie that didn't try to do too much which made for a very original and entertaining film.
First off, they may have marketed this movie as a horror but it is definitely just a well done psychological thriller. If you're looking for a typical scary movie, you might want to look elsewhere.
As a psychological thriller though, this film is awesome. Creepy atmosphere and cinematography gives mixed with a story that is solid provides for an engaging watch. The acting got kinda spotty at times (We get it, you're scared....you can dial back the over-acting!)
Other than that, I would certainly recommend this one for anyone looking for a damn good thriller. Way better than most I've seen recently that's for sure!
