Usually a "festival film", as in a motion picture created to win a prize at a more or less prestigious film gathering, is a way to express what's inside a director's/writer's mind. To convey a message. To expose a feeling. This film is different and unfortunately it indicates the arrival of a certain kind of cinematography. It was made to capitalize on a hot topic, in this case conservative parenting.
It doesn't even hide its bias too much. Instead of the normally accepted practice of leaving the finale open for debate of what it's all about, the creators simply and crudely slapped a subtitle openly saying what they want us to think. They had an agenda to push and they did just that.
As a film it's absolutely hopeless. The script, the production design, the cast, the music, even sound effects - all bad. They wanted to create a cold atmosphere through modernist surroundings... and failed. They wanted us to hate the antagonists... and failed to even explain what exactly they do that's so wrong. They wanted us to sympathize with the protagonist... and failed to even define what they hell she's doing there. The entire production seems rushed and badly thought through.
