This should not be categorized as a horror movie. You can see from other reviews that people are upset at their expectations not being met. Although it does have some horror-like scares, it is a different experience altogether, more of a character study. However, the way that the story unfolds requires patience and an open mind. There are some allegorical elements that are not explicitly made clear in the movie. This could lead to some viewers feeling like the story leaves too many details unexplained. I thought it was well-written and gave an interesting look into the experience of a young Mexican woman dealing with the limited options imposed on her by family and society. The few supernatural elements sprinkled in are a smaller part of the story, which is mostly a psychological drama. I ended up liking the main character, so that influenced my enjoyment of the film, but not every viewer is going to understand or support her choices.
