Shows how South American cinema is evolving. I didn't expect anything from this movie and it surprised me, although the lack of budget or quality of effects of "Hollywood" is noticeable, the movie hides them quite well. With a suspenseful plot that leaves you very uncomfortable for several moments, which I think is the best way to scare you in the cinema. If we get very critical, we notice that there are some gaps in the script or perhaps some things that we do not end up closing 100%. I recommend watching it with the perception that it is a low-budget film and that in South America horror movies-Zombies are very poor. I feel that it is an important starting point and we must support it.
