Okay, awesome work by the cast and by the writers in coming up with a finale like this one. Not only it gives us the feeling that it has ended, but it also gives us the feeling that something else will happen, even after the end.
I was really happy to see so many actors making a come back, even for just one last round (too bad Cuddy did not appear, but you can't always have what you want), and the songs were so appropriate for the occasion.
I give this one a very big 10, which is the same score I gave the series. You'll be missed, Doc!
