When Michael left Dunder Mifflin to start his company he thought (or in his case didn't think it all the way through) his new company would be successful right away. While he along with Pam were able to make some headway and steal some clients from Dunder Mifflin,the stragety prooved to be the end of the company. I liked that this storyline ended when it did.
Before this happens, David Wallace in makes an offer to buy the company. I think how Michael handled the neogations were done beautifully and shows how much he has grown. If this happened even two years ago somehow he or someone else (but probably him) would spoil the beans. I also enjoyed how when Jim told the people at Michael Scott Paper Company that David was considering buying out the company, that he ignored (on purpose) how the company struggled. Of course he did this mostly for Pam. Speaking of Jim, Charles realizes that he is not screwup he thought Jim was. He also realizes how Dwight really is. It was very funny that Dwight thought getting revenge on the Michael Scott Paper Company was by getting bees. Another part I liked was how he got Pam as a salesperson.
I also loved how Michael did the same thing to Charles that Charles did to him when he left. It was also good to see how much of a suckup Charles was to David.
Overall there were very good moments to this episodes with no major complaints.
