On the team writing thing I agree, and like others I can detect it and it can spoil it for me. Going for the big hit one liners all the time is wearing, what the Brits like is a story with our favourite characters and their trademark traits or faults and failings and idiotic lines. Something personal.
As good as Frasier and Big Bang are they're not really celebrating losers but winners with flaws. Could they ever commission a Frank Spencer or Alan Partridge, real losers? Doesn't seem likely. A Porridge? Never! Fletcher's a winner but a convict, the Americans won't promote that. OFAH's non commissioning is proof they have rules on who they will celebrate. Happily we don't, within reason. And we do love a loser. Characters I think the Americans are missing out on.
