Having finally gotten around to watching the series, which led to a marathon of watching everything from the first episode up to the most recent episode in just under three months I don't know if I want to even speculate, or listen to others speculate, about how the series will wrap-up.
For me most of the pleasure of watching an episode of "Breaking Bad" has always been spending forty-four minutes thinking how much it's like a finely presented Shakespearean tragedy, followed by suddenly jumping up and down screaming, "HOLY SHIT! THAT DID NOT JUST HAPPEN! I DIDN'T EXPECT THAT! START THE NEXT EPISODE!" while the credits roll.
