I have mixed feelings after watching the movie. I had no high expectations, so I wasn't disappointed - overally, a decent crime thriller, but the one, which you probably will forget. There are some original ideas, and a magnetic charater of a main villain, a gangster boss and a sexual deviant, who killed and mutilated a young girl Monika. Or maybe did he not?
A great acting was performed by Monika's mother, Helena, an acknowledged Polish actress Maja Ostaszewska. Her character is a family court judge, with a broken own family life, who tries to seek the truth. Performances of the rest of the cast were good, but rather forgetable. The victim, which we get to know better from flashbacks, a young actress Zofia Jastrzebska, did well in difficult graphic violence and nudity scenes.
Script writer and filmmakers had an interesting general plot, but at times I had an impression, that they lacked an idea how to develop the action. Especially it was visible well before the end of the movie, when the police seem to enjoy an easy success against the main suspect, and the tension breaks. Some will find an interesting plot twist, some - incredible plot holes.
All in all, a decent film to watch. Luckilly, the producers didn't develop it into a mini series, what would have been a waste of time.
