Why you talking about Jem, that ain't a horror movie?
personally I found 2015 to be very disappointing, pretty much every movie I was looking forwards to turned out to be mediocre.
In fairness, I was so bored I could have missed dialog but I doubt it. I honestly think the found footage became this movies worst enemy as it makes it hard to deliver exposition scenes.
I'm probably being a little harsh as the climax was quite good but the build up is so boring. At times you are literally watching people watching the 3rd movie.
