This is a movie that seems to have no purpose. The way that the sound effects were generated in the film is mildly interesting, and the xenophobia that the main character experienced made me believe that the storyline would go somewhere. However, this was not the case. Sitting through this, I found it hard to understand why the actors were even drawn to the material; it is so uninteresting. Technically the film has its merits, and it might be relevant for someone who has worked as a sound effects technician and editor in movies, but for the general population it is probably a waste of time. I know that it contains references to Italian horror movies of the 70's and 80's, but so what? My advice is to stay away.
