The acting is great. The movie is a bit slow for me however. There are also a few jump scares, unlike what others have claimed by here.

Rating: 6/10 (6 October 2016)

What went we out into this movie to find? We travailed a vast horror. For what? For what?
If you went in to this movie knowing nothing, within the first 4 minutes you could tell it was a horror movie by the soundtrack alone. I don't really like this approach, because the soundtrack spoils the mood. In fact, the soundtrack precedes the actual mood of the film. You could argue it is creating the mood, sure, but I would rather let the story organically form to create the mood.
From the start of the movie, the woods are the central horror of the unknown. After all, the family is being banished into the woods. There are several long shots of the woods with droning violin music.
(Usually when naked babies appear in a film, they are male for some reason. I'm too afraid to google "naked babies in film" but it's for sure a trend. Draw your own conclusions.)
The effects of isolation are immediately shown on the banished, isolated family. A young boy, Caleb, takes a peek of his sister's (Thomasin's) breasts as the camera zooms in because she is the most fertile female. He peeks at her many times. Thomasin exhibits motherly behavior toward Caleb. The mother brings up this fact. She is jealous that she is growing old. And she notices Caleb looking and blames the girl as tempting him. But can you blame Caleb really?
The dialect is quite good in this movie. But since it's authentic, it also might require subtitles for one to understand easier.
The setting of this movie is always overcast. Many horror movies just lower the contrast and hope that it will seem scarier. To me, this seems a bit overdone.
I suspect that that rabbit is possessed by the Witch of the forest. You can tell this because of the rabbit's eyes. The goat also has peculiar eyes at one point.
The ending to this is unsatisfying. Nothing really gets explained, the plot lines go nowhere. We don't even really know if 1 person is dead or alive except Caleb. 6.3/10
