My lovely wife and I are on Episode 4, really enjoying it.
I can't stand James Nesbitt, with his silly hair and his onse-size-fits-all acting, but I'll tolerate him for this.
I only know Cush Jumbo from The Good Wife, thought she was American!
I do love Eddie Izard as an actor, not as a comedian.
The idea of different locations strung together is common, and only 'jarring' if you actually know where they are, which is only ever going to be about ten per cent of the people who watch it, no-one else has a clue.
I remember a wondeful series called A Very Peculiar Practice which was set, I think, in Cambridge, but actually filmed where I live.
So there were shots of Newcastle-under-Lyme town centre, intercut with scenes filmed at Keele University a couple of miles up the road.
Not a bar to watching in any way, but some people find things like tat off-putting.
