I've read complaints that the end was predictable. That's not a problem in a finale, imo. I expected Neal would fake his own death to begin life somewhere else. To me, the path was set a long time ago and, as plot elements that have been foreshadowed should, it happened. To me, that's satisfying. And I'm happy that everyone lived somewhat happily ever after. I have seen more than enough endings that come out of nowhere so the showrunner can play gritty auteur and/or provide shock for the sake of shock.
Thinking of USA shows in particular, I'm glad WC hewed closer to Psych than the fuckedupness of Burn Notice.
