Weirdly enough, this Mexican horror film works quite well, not because of its paranormal elements, which do feature some impressive effects, particularly toward the end, or its disappointingly unthreatening rabid dog.

Instead, the film’s true horror lies in its insufferable pair of kids, their incompetent mother, and the downright hateful array of secondary characters.

A fun disclaimer appears at the end of the credits, where Emilio Portes amusingly notes that people in real life are even more awful than those portrayed in the movie.
