In my opinion, the show didn't jump the shark with the New York vs. New Jersey war, per se, but how they went about it. By that I mean, they set up everything perfectly at the end of Season 5. A regular 13 episode final season would have been perfect to follow that through to the end. But Chase and Co. took the money, putting $ over quality, and gave us a two-part final season with 9 additional episodes...resulting in a lot of down/wasted time. Then they speed things up way too fast towards the end.
Agree. Far too many new major characters in between Seasons 5 and the two halves of Season 6, and they never get developed fully. Hell, even Walden Belfiore, who did the final hit of the series, seemingly appeared out of thin air just before Christopher died.
