SPOILERS!
I was totally engaged in this drama, thanks to the brilliant script writing of Russell T Davies. Alan Cumming and David Morrisey were given two quite extreme characters who were not stereotyped at all. I felt for all of the characters, trapped in their societally-driven roles. The script and editing allowed the audience to understand where each was coming from.
The other characters were all superb too. The younger son who couldn't be honest about his sexuality and who was forced to defend himself against the bully in the football hooligan tribe who had guessed that he was gay by humiliating him; Leo's good friend, Stephanie who wasn't afraid to challenge him, and near the end, expressed the opinion of another poster here - why have you got to act SO gay? You could feel Leo's hurt that even she didn't get him.
Then there was the role of the internet: the older son to make money through what I would see as pornography (especially when he involved another person who looked drunk or drugged); Leo to find partners, suitable or not and how vulnerable that made him; the younger son to explore his sexuality and being 'outed' unintentionally; the Mum and Dad to fill gaps in their relationship with each other; the bunkum conspiracy theories that David Morrisey's character had read online about the 'non-existence' of HIV, Covid etc.
The football 'gang' scenes towards the end were very powerful in showing the escalating craziness that sometimes takes over a group of men (I think it is men usually), and the responses of the individuals in the group. We were shown that some of them were appalled by the lynching, but were powerless to stop it and were therefore part of it. I thought then of not just homophobic crime, but the racial atrocities of the KKK amongst others and what terrible things people are capable of in a group.
I can't say I 'enjoyed' this drama but I had to watch all of it, uncomfortable though it was, and it certainly made me think. I agree it should receive some kind of award.
