There Are Monsters is basically found footage meets Invasion Of The Body Snatchers - and that's no bad thing.
Four friends are filming a documentary about school children (or something like that) when during their filming they begin to notice odd, subtle behaviours in people. The subtle gradually becomes more in your face and outlandish as it becomes apparent that these people aren't actually people at all - they used to be - but now they have been taken over by forces unknown. The four friends eventually become convinced something is very wrong; and as society crumbles around them they end up fighting for their very survival.
There Are Monsters is an above average found footage horror. The acting, plot and pacing of the film are all very good. And the spin on the well worn found footage path that people are gradually being taken over by something unknown brings a freshness to this often stale sub genre.
The one flaw that's apparent throughout is the overuse of shakey cam. At times it's really difficult to actually know what's going on due to the camera flying all over the place, and there are one or two blackout scenes too when you can't see anything. I know this adds to the realism, but at times the shakey cam is so rough it's difficult to watch.
In the main though this is a very good example of how to produce a good found footage film, and with so many bad examples out there, this is a definite diamond in the rough.
