Coming from Poland, I believe show did a good show making it viewable for anyone around the world. The cast as young and older versions match, so their performances makes you care for ark of their characters. With six episodes, I found the show very bingeable. Young Pawel (Hubert Milkowski) and Laura (Wiktoria Filus) performances standout as grieving young lovers with guilt.
I did feel, as there were four stories going at the same time; Past camp murder and disappearance of kids, Past story about his mother, Present rape prosecution case and then Present Police investigation into him in reference to new death made it bit complicated as story's focus keep shifting to all these four elements and the current rape prosecution case ends on very lacklustre result.
If the story focused primary was on past camp mystery and current murder case it would have intensified the series as they should have been the prime focus due to their connection. Overall, the show is a good attempt and doesn't disappoint.
