The brits have put out duds for sure. I think there are a number of strengths they have that we don't.
1. Not afraid to use senior actors/actresses as leading characters (Waiting For God
, As Time Goes By
, Keeping Up Appearances
), which tends to remove barriers of having to look good in every shot (Friends
, and the equivalents thereof).
2. They've been able to pull off some Sci-Fi comedies (Red Dwarf
, and yes, I would include Doctor Who
). The closest we've done that I can think of is Third Rock From The Sun
, which I have a strange hunch was not that funny ( I never really watched it).
3. A show not designated as a comedy can be very funny (Doctor Who
, Rumpole Of The Bailey
4. The ability to pull off historical themes. The brits were able to produce a successful renaissance era comedy (The Black Adder
). We haven't produced any comedy westerns
, or pilgrim/founding father
comedies. I have to admit though, that the Brits attempted another Renaissance era comedy that was a flop.
5. I don't think we have anything like Monty Python's Flying Circus
