This film should have been garbage, it is a new take on an old concept but the trailers weren't spectacular and seemed like a film that belongs in the horror wasteland of January.
However, to be entirely honest it really isn't that bad and it's fair to say that for the most part it exceeded my low expectations. The central performance was quite good and most of the first and second act was pretty tense. The setting is solid and the director clearly was genuinely trying.
That being said, the film does become extremely predictable, and not all the scares land. The third act explodes into cliche, and there are perhaps too many plot holes for me to just ignore.
Overall, The Possession of Hannah Grace is better than the trailers suggest, it's a well acted enjoyable ride and does have some good scares, but the frequent jump scares, predictable flow of events and plot holes prevent this film from being anything memorable.
