I thought it was very well made. Stephen Merchant was very good at playing a creepy murderer, and I must admit I had my doubts when I heard he was playing that role.
It's just so depressing that it was all real. The Police were overloaded, but I think there was an element of homophobia there, too. Very much a "oh well, that's what these people are like" type of attitude.
The part where one of the guy's partner had to say "gay men aren't all the same" brought it home to me. I'm gay and I've never taken a single illegal drug in my life - I wouldn't have a clue about any of them, but I've had people make generalisations about me too just because of my sexuality. You kind of get used to it, but you shouldn't.
It's good Port got a whole life term, so he'll rot in jail for the rest of his life, as he should.
