If I’m being honest most limited series I’ve watched was uniquely great, some better than others but always something that’s caught me onto the storyline. In adolescence I was bored very early on, I couldn’t get emotionally tugged on by any of the actors and I didn’t even think the acting was that good (everyone said how brilliant it was). There was so much that could have been great but again just boring, I thought the parents had raised a shut down and angry child, which is probably the case with many children that go to knives or other weapons. I think it just shown me awareness that if you’re not careful with how you are being around and to your child. They will either turn out a product of all your issues or the complete opposite.
I would recommend the film or watch it again.
