Without revealing to much iot would be fair to say this is a movie about trolls.
The central conceit is that Trolls are real, but there existence is kept secret by the Norweigian Govt.
The film is made in a Blair Witch style with a group of students and a camera following the action.
I really enjoyed this film, it had some good jokes and a different feel. None of the actors were known to me, and with the subtitles on, it worked very well.
Of course the budget wasn#t massive, but the special effects worked.
If you have a spare couples of hours, you could spend it doing worse things than watching this film
