It's a great movie. About fat and thin trolls. Uses some of their tricks. For example, at the beginning and at the end, they covered themselves with quite a few compliments - experts studied for a year and came to the conclusion that the recordings were real. Yeah, you can't praise yourself. . .
It was really nice that there was no familiar face in the picture. In general, I believe that all films should be done this way, and not when one actor (which almost automatically means one character) for 20 films. If I were a director, I would only hire unknown actors. Played just fine. Very good camera work - and the effect of real shooting is recreated and at the same time does not shake too much when not necessary. The graphics are also testable - there was not a single moment where I could say that I saw a setup.
One of the downsides is some tightness. There are also problems with the scientific aspects, for example, if trolls are killed by light, how do they exist during the day? It is logical to assume that they are hiding in caves, but how can a monster of 100 meters tall do this? The size of the final boss was clearly too much. And it is not clear how in such a small country can exist populations of almost a dozen species of such huge creatures, they simply would not have enough space. Why do trolls, transferred to a realistic plot, nourish an addiction to Christians - also a strange moment, it is that in the bodies of Christians there is some special substance? .
In general, a very high-quality atmospheric film, the topic is fully disclosed. The ending is a nice troll, by the way.
