I love The Office. That was the first “adult” comedy I ever watched, and I’ve probably seen it more than any other show. I adore it.
That said, the arc where Jim moves to Stamford is boring. None of the characters are good, and Jim’s relationship with Karen is just not gratifying after the arc they had just concluded.
The arc where Andy quits his job is far worse. He just loses the plot all of a sudden at the end of the show. Catherine Tate is amazing at playing Nellie, but the character is just simply infuriating after she takes over as manager. Which sucks because I loved the Sabre Store storyline, and I really think it may be one of the last compelling and funny arcs before the leadup to the finale.
