Sinister is about a writer that studies murders and also points out what the police miss while investigating. His family moves to a new city so he can study a brutal murder that also results in a missing child. During all of this he stumbles upon a pattern of murders along with a mystery face and symbols in what he studies. It is basically an occult type movie with a few good scares and some suspense. Also I was actually pretty happy about the way the movie ended. All in all I give it a 3 out of 5.
