Decent Found Footage Film
It is slow to establish characters and the inevitable weird element... But that works OK in this case. It is interesting to note how dated much of the internet storyline seems now, just ten years later, but period pieces are acceptable.
What you get here is an internet startup (Like youtube but with an even more aggressive and intrusive "personalization") that encounters what are intended to be really creepy anonymous postings. It is unfortunate that the postings - Screamer videos - are really quite familiar and tame, but if you can roll with it, the movie works pretty well.
