I usually watch Utopia, but I've never been 100% sure whether to fully endorse it. (Well, I did say I was enjoying it back in 2014. Perhaps my doubts are growing.)
It does have good acting, I think - with the possible exception of Rob Sitch, who has a very limited range - and some lines can be sharp and amusing, if not lol funny.
But the problem with the show is that it's still mainly a satire of Public Service managerialism (and secondarily, of political obsession with spin), but it feels that the heights of faith in managerialism are well in the past, perhaps by two or three decades now.
The result is that I never am sure whether the satire is accurate, or dated. Certainly, last week's episode, featuring the hoops that the female lead (I don't really remember any character's name) had to go through to get a promotion her boss had promised her struck me as relatively accurate from what I had heard of the public service from a friend in it - back in the 1980's. (And by the way, the female actor who was the HR person inventing procedural roadblocks was really good in a well written role, I thought.)
I'm not sure how anyone on the outside, who no longer knows anyone in the public service, finds out how the character of public service life has changed in recent decades. But I hope it has...
