Follows the mold of every single found footage stalker movie made just a little more oversimplified is all.
With a 30 minute plot (40 at the most) stretched out to 81 minutes and most scenes mainly being day to day scenes of the family doing regular things at home this movie is far more boring than it is disturbing.
The acting is... okay I guess, the family does act kind of like a family does. The stalker we only see from time to time and he's weird I guess, which makes sense.
