Its an overall good movie especially considering it is the first feature film attempt by the directors. But is far from perfect. The biggest (& possibly the only) flaw of the movie is its protaganist. She does not miss a single chance to act stupid & selfish and keeps getting everyone else into trouble. This makes watching the movie a frustrating experience at times. If there was a proper sensible character to counter her and was given as much screen time, movie would have been better. But on technical level, its a well made movie with nice effects, cinematography, acting & direction. In the end, if I was to rank this movie in comparison to other horror movies. I would rank it above any conjuring or insedious sequels but below movies like 'It Follows'.
