I'd move The Bodyguard to the bottom of that list. Well, that's a lie, I wouldn't recommend it. I honestly couldn't believe all the attention it got when it came out, so overrated. Killing Eve was out at the same time and way better. Happy Valley, Peaky Blinders and Fleabag are excellent. Luther and Line of Duty are very good. Taboo, I remember thinking it was fine, enjoyable enough. Though now I can't remember exactly what happened. I do remember it being a bit dark and mumblyOff the top of my head things we haven’t seen…
The Bodyguard
Happy Valley
Taboo
Peaky Blinders
Luther
Line of Duty
Fleabag
Any ITV dramas (I think they all look trash)
As for ITV dramas, I don't watch much on ITV but Unforgotten is excellent and there are 5 seasons. A Spy Among Friends is good too.
