If you like comedy,Are you Being served and Fawlty Towers still 2 gems from the 70’s.....
I’m not as big a fan of the British TV comedy, though I did ocassionally watch “As Time Goes By” and enjoyed it.
There are so many great British period pieces, full length, on YouTube, both movies and TV series. Glenda Jackson did a great series “Elizabeth R” from the 70’s. And there’s just too many to even list. For some reason the British are just excellent at acting, directing, scripts, sets, etc. And for the most part mostly mild action instead of CGI violence and bizarre occult happenings like Hollywood produces.
