IMO it's funny. So is How I met your mother, Rules of Engagement, and the Big Bang Theory, Shit my Dad says the new one with Shatner. The rating speak for themselves.
Ratings mean Jack shit, if that were true then reality shows are the gold standard. Shit is dumbed down...Shatner's is good, but Harry's Law top all of them. The Big Bang Theory is corny as fuck, and also helping to push the twink agenda as well...when Mayim Balik (sp) was on (herself a certified nerd who can't dress), that was the highlight of that show.
Basically all the good writers have gone---the best comedies are the satirical cartoons, or on cable.
Networks basically survive on their dramas---Fringe, House for Fox. The Law and Order spinoffs and Harry for NBC, CSI, NCIC, Numbers for CBS, and Grey's Anatomy for ABC. The real writing talent shows in the dramas, as that is prolly where the money is.
Sitcoms are only 30 Mins, and occupy time slots where they have to go against reality shows and American Idol type shows---thus, they are not provided with "strength", they are cannon fodder...
