Season 7 has been mostly terrible. The writers have focused too much on the love stories throughout the last few seasons and I could give a fuck. This show is cartoony and not remotely believable, so whenever they try and force some drama down our throats, it always tastes icky. I think the strength of the American Office is that they decided to go a more outlandish route for the sake of humor and it works whenever they're not trying to throw in needless drama. The more time they spend on the interpersonal relationships of these underdeveloped caricatures, the more the show tends to lag.
Also, needless dancing and singing is always a sign of a show running out of creative juice. Such as Dwight and Co. at the roller disco or the Office gang sending off Michael with a tearful ballad (Jesus Christ, that sure was forced almost as bad as the YouTube reenactment in the wedding episode). Regardless, this show just isn't funny anymore to begin with. Unfortunately, it will survive for eons since it has a crazed fanbase that will watch it for the next five years or whenever they decide to call it a day. I, on the other hand, will watch through the end of this season in order to be a completest and then bolt.
Also, why so much effort put into Michael leaving? There's been far too many poorly crafted Michael-centric episodes lately, presumably because Steve Carell is leaving the series. Except, he isn't because we all know Michael Scott will return in the final episode or two. Meh.
