I liked it but i dont like they way they handled the death of the daughter. It happens right in the beginning of the movie in a flashback/montage type sequence while the credits are still rolling and a weird music plays killing the mood.
You never got a connection between the daughter and the parents, you never got to see the love and therefore you cant connect with them yourselves and feel for them for the loss of their daughter which is bad because her death is the catalyst for everything they do later on and the events that follows.
It also seemed to be in a hurry to get to the ending and rushed through all the storytelling. Certain elements of it just felt out of place and presented wrong because of that. Also that weird music thing i mentioned plays a lot during scenes that would have been scarier if there had been only silence. It also rips off Pet Semetary.
Not terrible but it had the potential to be really good and in the end it was only okay.
