In general, all found footage films require you to lower your expectations. The very nature of this method of filming is to eliminate the need for special effects, large crews and complicated staging.
"Found footage" is synonymous with "Expect less." That being said, the exercise in minimalism has a tendency to refine and strengthen plots and is more demanding on the actors. So there are strengths that arise.
This film shows few of those strengths. The acting is not abhorrent, it's reasonable, but still remained unbelievable. It felt as though it was trying too hard. My personal feeling is that the acting failed because the plot itself was unbelievable and didn't really hold it's own. There are simply too many holes in the idea. Tiny little questions that you end up asking yourself that pull you out of the illusion. "Why did he say that? Why did they do this? Why would ANYBODY do this?" Every found footage film's greatest challenge is a battle with common sense. If the actors don't behave in the way that any normal person would, then the illusion is destroyed. There are simply too many places where common sense doesn't prevail.
That and the predictability of the plot kept making me wonder why the actors didn't see it coming. It was fairly obvious which direction this was going to end up going.
And lastly, poor choices by the editors. Your movie can't appear to be real when the camera angles keep shifting but the SOUND doesn't alter.
It came off as weak. Or even worse, it was unremarkable.
