Very nice send off. Humorous, emotional, poignant, and it finishes the character arcs nicely. Raj didn't get much play in the final, but is that a bad thing? Howard and Bernadette's pettiness and scheming come into play briefly, and we see how far Sheldon and Penny have matured.
The only thing that would have made this better is if Sheldon looked up at the Nobel Prize ceremony and Professor Proton's ghost was in the back of the room giving him a thumb's up!
