Tho' the neologism is one I've never warmed to, the term "dramedy"* might be more apropos to this ongoing series than "sitcom", especially since the characters round these parts are nothing if not fully-rounded and complex rather than stereotypes and cut-out figures. (Besides, I think the sitcom's obligatory laugh-track would drive us all nuts in short order!)

*A term I first heard in reference to Blair Brown's series of some years back, 'The Days and Nights of ???'
