I found this movie to be quite entertaining and would like to watch it again sometime. It tells a fairly straightforward adventure story with good writing and fine acting, and even as they fill us in on the folklore of trolls, they don’t weigh us down with it. There is a delay before the total reveal of the creatures and it is worth the wait. I am not a self-proclaimed authority in special effects, but I thought they did a great job. Horror is included in the genre description, but it is not the sort of gory horror film I usually avoid. I see there is a new movie out on the subject, so it might be interesting to compare the two.
