If you're watching this because it's "based on a true story" then don't bother because it's a pack of lies. The "investigators" the Warren's are fake and have been outed on a number of occasions. The family, particularly Andrea Perron, seems motivated by promoting her own book. The truth is well laid out by the current owners of the property (whose lives have been made miserable by the unwanted attention of kooks following the release of the film) in a video here https://www.youtube.com/watch?v=w2dg2Ufavj8

By all means watch it and enjoy it as a decent horror movie but don't be fooled and conned by the makers into believing that there's any truth in any of it!

In the bonus features the makers of the film assert that they wanted to make a film about a human story rather than a story about the issue of slavery. To me this is an artificial separation. Slavery IS a human story particularly when dealing with a specific case and since the whole circumstance of this girl is about her slavery you cannot but tackle the issue as well. By making the characters so black and white it detracts from rather than adding to the realism. The unrelenting cruelty by otherwise "normal" people isn't explored properly because in real life such people convince themselves that what they're doing isn't cruel at all. Exploring these characters in greater depth would have forced the film to examine the issue more deeply and made the human story that much more powerful and realistic. Definitely worth watching despite these caveats.
