Time Out says
This Swedish horror-comedy is played for laughs, with talking dogs, garden gnome-throwing and over-the-top gore. Dragged to Lapland by her doctor mother, who is keen to work with reclusive geneticist Professor Beckert, teenager Saga (Grete Havnesköld) is befriended by Goth girl Vega (Emma Åberg) and her side-kick Sebastian, who works at the local hospital. But at the end-of-term party, Sebastian steals pills from the professor’s stash that have unexpected side-effects. Fangs go from bad to worse, as the high school pill-poppers develop enhanced vision and acute hearing, together with a craving for fresh blood.
Director Anders Banke cites as an influence ‘An American Werewolf in London’, but don’t get your hopes up. He and his scriptwriters play fast and loose with the rules, while delivering sporadic bite-size scares.
