Not to my taste, I think Life Of Brian was probably their peak IMO, but it’s not really as good as I remember it being – whenever I watch it now (4-5 years since the last time usually) I rarely watch more than half an hour of it.
I always thought the TV series was crap, Holy Grail wasn’t much better.
I couldn’t stand Fawlty Towers either.
Perhaps my taste is more mainstream, if I’m in the mood for a bit of 70’s comedy nostalgia I always enjoy the Two Ronnie’s, Morecombe and Wise or Porridge / Open all hours. Those sorts of things, are so obviously ‘of their time’ but timeless at the same time.
