Last night's episode was not great. It was mediocre. The show has fallen apart since one of the biggest draws, the Jim/Pam/Roy conflict, fell apart. The show is relying very heavily on Michael/Dwight to carry the comedy and it just doesn't work for me. I could has stopped watching the show after the writers strike, TBH.
Hopefully I won't get torn apart by the rabid fangirls of the show (wife included) when I say that the show is a shadow of it's former self from the high of the second season. Season 5 will be the last season for both Office and Earl. The show will end with Michael getting back together with Jan, Michael taking Ryan's job, Jim taking Michael's job, Pam leaving the office after her and Jim get married or engaged and Dwight and Andy fighting it out for the "Assistant to the Regional Manager" position, with Dwight ultimately winning and getting back together with Angela over the course of a season-long story line. Andy will probably try to commit suicide but fail.
There's only two choices for the Jim/Pam thing.
1) Get it out of the way quickly to concentrate on the other story lines
2) Concentrate on other story lines quickly while leaving Jim/Pam on the back burner and resolving it within the last 5 episodes of the series.
The focus of this show is simply not Jim/Pam any longer. It's Michael, and it suffers for it.
