Pantoliano and Buscemi were great, fantastic acting all round, with Gandolfini, Imperioli and Edie Falco
Their characters weren't explored enough though, or properly possibly due to different directors in a merry-go-round. Not enough continuity, sometimes things didn't follow, and I agree, Breaking Bad doesn't have that flaw
But I still think the whole concept, the characters, storyline, my favourite.
