This show was a bit more kitchen-sinky than shows I'd normally watch - it reminded me a bit of stuff by Ken Loach or Mike Leigh, but I liked Adolescence a lot more than their films (even though I realise that their output is highly regarded).
I've seen a fair bit of negativity about it in these kinds of online spaces, so I imagine that I'm going against the grain by saying that I'd recommend it. It's best to know as little about it as possible beforehand though - not just about the story beats, but also don't buy into the hype about it and expect too much of it.
