Horror movie versions of puberty have been done well in the past, Wildling however misses the mark.
Final rating: - Had some things that appeal to me, but a poor finished product.

Good watch, could watch again, and can recommend.
Trigger warning: This does have some aspects of kidnapping, and sexual assault.
Bel Powley is amazing, and really carries the movie. Liv Tyler does a great caring mother role, Brad Dourif is sufficiently creepy, and Collin Kelly-Sordelet is an angsty teen, but James Le Gros is more interesting than they are without saying much at all. The support characters are here more to facilitate the mechanics of the story, and its not that the story is poorly written, it is just focused.
The establishing act is brutal because we know what is happening to her, and everything past that is centered on her transformation, and presented amazingly.
