Say it isn't so, Walter White. Walt and Jesse leaving our Sunday nights? Sigh. "Breaking Bad," one of television's absolute best - and darkest - series airs the first show in its final season at 7 p.m. Sunday on AMC. You'd better call Saul (who might get his own series BTW), don your Heisenberg hat, order a rooftop pizza and slow cook some Los Pollos Hermanos chicken as you say farewell. Even star Bryan Cranston is blue: He has cooked up his last recipe.
