Mindy Project is actually excellent. IF, and it will be a big IF, you can find Traffic lights, really good 13 ep show from the states with a good cast. Massive shame it got cancelled, 2-3 years old probably.
The League is along the lines of Sunny, not quite as extreme but the same feel to it, Sports Night if you haven't seen it, late 90's Sorkin comedy, you can buy it, not sure about download anywhere. Party Down, excellent. Episodes if you haven't watched it, couple good english people in the states working as writers, its got Matt le Blanc in it, but he's playing himself rather than one of his stupid characters and is excellent in it,.
Bored to Death, Better off Ted, again harder to find, finished a couple years ago, Bored had 3 series I think, Ted had 2, both excellent.
How I met your mother is just woeful, it was actually almost decent for 2, even 3 years, its been diabolically awful since then, Big Bang Theory is an abomination, Californication is pretty awesome. Ben and Kate is surprisingly good, takes a bit of time to get into it as at first I just found everyone irritating, but after a couple eps it just works.
