I thought the ending was appropriate. The show is all about how you never know what life is going to throw at you...and leaving the ending blank was perfect. Whether Tony got some soggy french fries or a bullet in the head - it doesn't matter - you never know whats coming around the corner so you should take every moment that you can. That was touched on in the episode too when Tony was in his backyard raking leaves, just starting at the sky and trees and taking it all in. Just my .02
