Having watched this after finding out the show's future was in jeopardy, I sort of see why.
Obviously it's hard for a new show to establish characters and be extremely funny, but this was leanign more towards the former.
The jokes weren't to the best and to have seen Kelsey and Patricia in very funny series before ("Frasier" and "Everybody Loves Raymond", respectively) I found this sometimes hard to watch. It was like watching an average crossover episode.
Also, with Chuck and Kelly having slept together, it was an easy guess to say that Kelly's daughter was Chuck's. I guess every show needs some sort of story arc, even if it is as weak as this.
I probably will watch the next one, just to see if there's any improvement!
