I rated this episode high because I'm A Fan of this tv show and all of the actors/players.
Sure not every episode is a 10 but 99% is.
And I realy think that because of the ending of the closer the last episode will not be as good as all the others.
At the moment I'm watching the old ones, season 5 and 6.
I will miss them all, so my rating will be high even if i think its a bad episode!
