My british comedy recommend is The IT Crowd. Followed by The Mighty Boosh. Coupling cuz Jeff. All are available for streaming.
Of course, Red Dwarf. Not so much the later seasons, but the first few are gold.
Red Dwarf & TMB are fantastic shows!!
British comedy is my wheelhouse, so many recommends... will always love
Spaced,
Green Wing is awesome (featuring Michelle Gomez at her most unhinged) and
That Mitchell & Webb Look is still my favourite sketch show.
If you want to go old school,
Blackadder still holds up well (just skip season 1), so does the original
Yes Minister, although the wry satire doesn't really translate to batshit insane hellscape that is UK & US politics is in 2020...
Could go on and on but will cease rambling there.
