I watched the US version of The Office until Steve Carell left. The last episode I watched, prior to last week's finale, was "Goodbye, Michael" in season seven.
I did something similar with ER. I followed and enjoyed ER until Dr. Mark Greene died. That was it for me. I felt no need to continue watching, although I did return for the seres finale.
The Office finale, which I just watched yesterday, was very well done. It was sweet, funny and sad with just the right amount of nostalgia and closure. The return of Michael Scott was the icing on the cake.
Did you see The Office finale? What did you think?
