The Ken Burns Vietnam doc that Batfink mentions is indeed excellent, takes a bit of getting through, but really thorough and beatifully made.
I've never met anyone else who watched Person of Interest. I'm not sure how I found out about it, or if it was properly broadcast over here, but it's properly excellent. Network telly from the states, so suffers from 'we need to make 24 episodes a seson' syndrome slightly, but really well done show about pervasive surviellance, the possiblities that might lead to and shooting peole in the knee a lot.. From the mind of Jonathan Nolan (who did the new Westworld thing) and has Jim Caviziel in. Not as highbrow or dense as yer Wire and the like, but not braindead either.

TV
Arcane (netflix league of legends based animation (don't let that put you off)). Knew nothing about it & hadn't played the game but amazing animation, action & great story.
Queens Gambit
West wing / the Wire (tho not seen either for a while)
Chernobyl
30 Rock / Parks & Rec / Arrested Development (not every series is great (think some were subject to the US writers strike) but the majority are brilliant with lots of great characters & re watch value) 'there's always money in the banana stand'
Severance (if only for the final 5 minutes of the last episode. Proper tense wow TV)
