I thought it was a very good episode all around.
I tell ya, the part I enjoyed the most was when Carter was looking at slides, and there were pics of the golden age of the show, when Clooney, and Edwards were still on.
All in All a nice send off for Carter. Although its not the last we see of him. He said he will be back next season for like 4 episodes to clean up some left over issues. Probably with that center they are building
