The 1950s/60s US comedies like Griffith were a flop in the UK, we found and find them far too twee. The one we loved and love is Bilko.
If by “twee” you mean American TV comedy is/was cloying,
terrified of sex, politically correct, poorly written, and (with few exceptions) derivative and unfunny, then, yep.
“Twee”??
Like “treacle”?
