My wife and I spent a good chunk of the holidays catching up on this show. She is Colombian, so the whole concept of drug cartels is pretty "meh" for her, but I'm an innocent Canadian and was completely hooked after the first episode. I found bits of season 3 to be a tad slow, however season 4 from start to finish was fantastic. I had thought it was over and done with until I read that a final season of 16 episodes will begin in January. My guess for the main story is a cat and mouse angle between Hank and Walter, with Jessie trying to move away. At any rate I can't imagine it being better than season 4 (how often do you hear about drug dealers wanting to kill you??) but I'm looking forward to being proved wrong.
