I'd rate it with 1 star because of the script, but the idea could be interesting and it might be worth to watch it.. Also, Rudolf Frecska's performance makes the film. The problem is that there are a lot of characters and all of them are just shadows, that takes the movie to arbitrary decisions. The script is very poor; as it starts with a death, keeps trying to impact always in an easy way.
It's essentially about a man who realises his son is a monster yet is driven by his parental nature to protect him. Not a patch on 'Delta'. His signature is still all over it (pushing characters into uncomfortable and often ambiguous motivational territory). I have no issues with minimal backstory. The camera work is excellent, it's just a lack of character development that lets the film down. 2.5 stars
