The film was advertised as a domestic horror film and the mood and the location was very well met. In terms of action, the whole film takes place on a farm in the countryside (Lower Austria), the actors are all very convincing and were well chosen. Pia Hierzegger is of course fantastic as the aunt, very believable.
The label horror film is too strong for me, although it certainly fits into the genre, but measured against today's usual horror films, the film is already rather harmless, more psychological thriller. Also, the film offers little surprising.
The story: overweight teenager Simi visits aunt Claudia, a nutrition expert, in the countryside (with hopes to be helped with dieting), with (newly married) uncle Stefan and cousin Fillip (from the first marriage of the aunt). Simi feels uncomfortable from the beginning, the cousin a creep, the aunt strict, the uncle too nice?
I felt they got inspired by films like "Get Out," "The Wicker Man," as well as some Hammer films from the sixties. Without giving more away, you definitely guess what the whole thing is leading up to in the course of the film. That's what I meant by unsurprising. I was missing a twist that would change your view of the story and question your perception, so to speak, but that twist doesn't come. Conclusion: well done, but not top notch.
