The whole "found footage" thing has worked, maybe, twice, with "The Blair Witch Project" and "Cloverfield" being the only two I found watchable.
The trick is that, there can be some merit in the "found footage" concept. But, it has to be executed by skilled filmmakers. In "Cloverfield," for example, what worked is that the movie was shot with Sony F3 Digital Cine Cameras. These are full-size cinema cameras. And, for the most part, the cameramen kept the shooting straight-forward. It was handheld, but competently hand held by people who knew how to shoot. The movie had just enough of that hand-held quality to support the "found footage" premise. So, you bought it as an audience. While, in reality, people who have shot movies know that doing the professional job the camermen did on "Cloverfield" requires actual skill.
All these other movies just want things super shaky, and super annoying!
