Oh, it wasn't that bad. Tied most of the relationships up with a bow, and the Buffy appearances were funny to me. I guess the main thing was that Sheldon finally realized the importance of friendship and having other people in his life, to the point of moving him to express it to the world. The very end I guess was to build unity among the group, but I do have to say that I didn't care for the slowed down version of the theme by BNL - should have ended up-beat.
