The plot and the acting were both adequate, and even very good in places. It had intermittent "Us" vibes here and there which were creepy enough. But what really drags my rating for this down is the camerawork.
"There Are Monsters" is what I call "quasi-found footage" - some scenes are supposed to be seen as if through the lens of one of the characters' camera, and for some scenes, it's obvious that no characters are recording it. If it were intended to be a bunch of amateurs, or kids, or anyone else who didn't know what they were doing, the camerawork might be somewhat excusable. But even in the "found" footage, the characters operating the cameras were supposed to be professional cameramen.
My ass they were. The movie was so shaky and blurry in so many places, it really took away from the decent work of the actors. No professional cameraman would produce work like that, even on a job they weren't taking all that seriously. As if that weren't bad enough, they continued the horrible camerawork even in scenes that weren't intended to be "found footage". For instance, the main female protagonist entered a bathroom stall at one point. She was completely alone, no other characters were in the booth to film her. It was a steady picture at some points, but a jumbled, chaotic slurry of motion and digital myopia for the most part. There was no excuse for that.
The only other thing I didn't like about it was the jump scares, but they didn't have more than maybe 5 of those. I just hate jump scares in their entirety, so that might be more of a "me" thing.
Over all, if extremely shaky camerawork doesn't bother you, then I would definitely recommend this for you. Otherwise, I'd give it a pass.
