I will mention a few spoilers but I really loved this movie so much and I can't tell you how much the book impacted me. What I loved about that movie is our main protagonist. She's definitely not a good person and she is more of an anti-hero. She lacks the capability of caring for other people that aren't her family and she doesn't have a moral compass that prevents her from taking her revenge. It's kinda like fighting poison with another poison. The kids ended up having their lives destroyed, or murdered, LOL. The child murdered didn't live a happy life either which made me really happy. It also shows how important child neglect is and the loopholes in the law that people take advantage of, moreover that it became a leeway for child murders "BecaUSe tHe laW pRotecTs THem". What you must love about this movie is the atmosphere. It's so poetic and gloomy that it sends a shiver down your spine! I recommended rewatching it because this is good shit!
