there were times when some of the shite Dwight did was straight up unrealistic and unbelievable.
I see where you're coming from, but if you go back and watch from the beginning, Dwight has more or less been like that the whole time. It was in the "good old days" of the show when Jim convinced him that you could buy Gay-dar at Sharper image, and that the Ben Franklin actor was the actual Ben Franklin. Where they went wrong with Dwight was when they made him the odd-but-smart ladder climber in the Sabre "era." Now, when they try to go back to the Dwight that believed he was receiving faxes from himself in the future, it seems fake and contrived.
With that said, I'm pumped for next week. There are very few shows that I've laughed at as much as The Office. And I feel like we should be past the point of criticism now. Just enjoy.
