I think one thing is that there have been a couple of really, gut hurling soppy bits, where you expect a Modern Family style reversal to undercut it, but they don't. And I'm probably still expecting Arnett to go full dick as I watch, which he obviously isn't going to do! It's a nice enough show though.
Just 'aquiring' some 'Up All Night', see what's happening!
The recent American comedies currently doing it for me, that I can remember off the top of my head, are:
Venture Brothers
Parks And Rec
Better Off Ted
Party Down
China.Il
The Heart She Holler
Community
30 Rock
Eastbound And Down
Curb
Louie
Tim And Eric
Modern Family
Big Bang Theory
Yeah, The Americans can do comedy.
Keep hearing about 'The League', I'll have to check it out.
