Not only is the costuming, script and general acting less than mediocre. The first perspective video blog/ recording style is basically a way to excuse the fact they were too lazy to film.
I would also like to question why these children, filming an unprofessional documentary have access to two of these expensive looking cameras. Like it just seems a bit unlikely and generally ruins entire concept of a DIY film project.
Despite that the film itself is slightly eerie and did make me jump a few times, and the plot is interesting for the most part.
