Season seven of The Office has thus far established three major storylines. The first one involves the inevitable reunion of Michael and Holly. The second one is Dwight having purchased the building. The third storyline, involves Pam's promotion to office administrator. In China, Pam's new position crossed with Dwight's ownership and management of the building.
The sixth season of The Office has been the weakest of all the seasons thus far. There have been storylines that have been started that did not continue until many episodes later, and other storylines that should have gone for much longer but did not. A lot of the problems lie in the writing, which led to the characterization gone wrong.
