Highly recommend, if you liked those, Poldark. The newer one. Shetland is meant to be good but I haven't seen it.

I also highly recommend Fleabag - quirky, and written by Phoebe Waller Bridge who plays the main character who's a bit of a legend.

THere's also a gorgeous sweet show called The Detectorists. If you want an antidote to US shows, this is absolutely it. When Jamie suggested it I was like - what, a show about metal detectorists? And it is one of the best shows I've seen ever - I laughed, and cried. Fuck I love this show soooo much. I often just play the theme tune, a song by Johnny Flynn, and plan playing it at Jamie's funeral, not that he's dying any time soon. He absolutely approves.

I mean, read some of the comments to the theme song alone

There's also some fantastic cop shows - Happy Valley, Line of Duty.

Don't worry, UK does violence and gangs too - Top Boy is fantastic London gang stuff, loved it - you may need the subtitles to interpret the patois though.

Anything else you want to know about British shows, let me know :P
