Thelma is categorized as a drama, fantasy and horror but I wouldn't categorize it as a horror movie because there are no horror moments at all. There is suspense building throughout the whole movie but it never gets really creepy. The story is good though, intriguing, slowly building to the climax. Good directing from Joachim Trier. Thelma is nicely shot, clearly done by professionals. The cast was well chosen as well, as all the actors did a good job with their respective characters. To me it could have been darker with more scary moments to make it better but even without that it's entertaining and worth watching. Good Norwegian movie.
