Very satisfying ending.
When Dwight turned around to see Michael..."that's what she said"...just perfect. Tears actually welled-up!
I agree with everyone else who said that his appearance was just right. They didn't have him go nuts or anything. It was very nicely done. "All my kids have grown up and married each other. It's every parent's dream!"
Everybody got a little something, which was nice. Meredith and her son at the bachelorette party...wow!
The friendship between Phyllis and Stanley.
Erin and her parents.
The even re-humanized Andy, which was good.
The only part I didn't like was Ryan's baby thing. That was unnecessary and kinda dumb, IMHO.
Overall, a solid A of a finale.
