This is a movie that improves dramatically when you realise it is based on a surprising true story.
Attempts to be another Blair Witch, and unfortunately doesn't get anywhere close.
Surprisingly good movie. Admittedly there are weaknesses in places, however the performance by Chastain pulls it all together in a very strong way.
Although formulaic in parts, it is done very well. There is a lot of clever film making behind this. If you have enjoyed Neesan's other work, you'll enjoy this.
