I believe The Office to be at its best when the writers balance the characters of the show. For example, I thought the PDA episode was up to the quality of the season two/three episodes. Michael and Holly were hilarious, but, not overbearing, Kevin was on his game, and the Jim and Pam sideplot was definitely humorous.
When comparing that episode to Threat Level Midnight, (An episode of which I had huge expectations.) The episode ended up spending way too much time on Michael and all of the characters became mere caricatures of themselves. The episode also suffers from the same fate if it focuses too much on Dwight, or Jim/Pam.
However, I will be a loyal follower of the show until the bitter end, and, I am still leaving out a faint glimmer of hope that it may find a new wind after Michael's departure.
