Best! Menggunakan teknik mockumentari ala Blair Witch Project dan Paranormal Activity. Troll memang lagenda di negara Scandinavia yang biasanya diadaptasi dalam filem-filem lainnya, mungkin jadi makhluk hodoh yang comel. Dalam filem ni, comel kurang, ganas lebih. Bila muncul di skrin, rasa teruja. Cuma ending kurang klimaks. Cinematography cantik, efek make believe yang baik.
A group of students set out to make a documentary about a supposed bear poacher, Hans. The students are following Hans through West Norway. When they try to interview him he tells them to go away, but they persist. As they follow him into a forest, they see flashing lights and hear roars from something larger than a bear. Hans comes running back to his vehicle, screaming "Troll!". They all seek refuge in the car, which is turned over, and the tires eaten. Afterwards, Hans asks the students to help him hunt down the troll that did this.
The next day the student meets up with Hans, who wants to make sure none of them are Christian, since the trolls can detect them by their smell. They assure him that they are not, and they return to the same forest as the night before. Hans points to a small brook and tells them to take off their clothes, wash themselves and lubricate themselves with artificial troll essence. After this they follow him deeper into the forest, where they are told to wait for further instructions. As they wait, they begin to think that Hans is playing a trick on them. Suddenly they see a bright flash, hear another roar and feel the ground shake. Out of the woods comes a giant troll with three heads. They flee back into the woods, where they hide as the troll smells after Christian blood. They return to Hans's car, where they see the troll turn to stone. They decide to help Hans to kill all the trolls that have broken out of their sanctuaries, and to find out why they have started to break out now and not earlier.
