Just watched...here's my take on the film
First of all, I love psychological films. I'm a crisis counselor, so right when I heard about this film the other day, I knew I had to see it.
The film was beautifully shot. The entire crew did an amazing job. The tension throughout was great and the periods of silence worked very well.
However, I sort of feel...indifferent about the ending. I'm not sure exactly how to feel about it. It felt like it ended right at the climax, but that seems to be what they were going for. I really liked the way that you weren't sure if the cult was following her or not, but I ultimately feel it was a bit weak to base the entire film around that. I think that if the film was 20 minutes longer and actually showed her come to terms with it and talk about it, the film would have been better. I kept waiting for a "it was horrible, they raped me, etc..." type scene but it never came. I felt there was no pay off. I keep thinking "what's the point? I come to know these characters and...that's it."
On to the good things. The depiction of a woman after going through a traumatic event such as this was amazingly accurate. Like I said, the film was beautifully shot and Olsen did a fantastic job here.
I get that they were trying to put you in the shoes of Martha, and it worked, but I would have preferred a less open ending than the one that was given. They still could have created the same tension and atmosphere and closed the ending better. I still really enjoyed it, though, but because of the abrupt ending, I can't really recommend this. Endings make the film in my opinion, and the pay off here was underwhelming.
