I think the last four to six episodes showed great improvement and really if you based this show on those episodes I would put it on par with some of the better or decent sitcoms on TV right now. The core casts timing and ensemble acting has improved a great deal and the premise certainly is one that could be sustained for some time.
Unfortunately the early episodes were weak and I think like a number of other shows early this season the scoring was low as some people who didn't even watch the show scored low ratings for it. It's called preconceived notions!
Thanks, Jeffery
