Warning! Personal opinion following: Breaking Bad is, if anything, one of the least predictable shows on television, in fact one of it's defining traits is the way in which a normal person reacts to the lack of predictability. One of the reasons the show does such a good job of creating tension is due to the fact that Walt (and several of the other folks on the show) are in way over their heads, so you never know if they will react to a situation that is clearly beyond their ability to deal with well.
In reality, both Breaking Bad and Mad Men are character drama's. They aren't shows about people working at "X" like 99% of TV and it's place "X" that the show actually revolves around. That means that their surroundings, be it drugs, zombies, the 60's or whathaveyou, are merely there to serve the characters and their stories and development. See, a show like Lost or 24 is about the thing, not the person. Law and Order is about following a narrative that never changes, not cops or crooks (the Wire was about cops and crooks, or more appropriately, people). Lost is about an island, not the people on the island. 24 is about crisis, not Jack Baeur (sp?). Jack B. is merely the vehicle through which we experience the crisis where on Breaking Bad, the drug game is the vehicle through which we delve into who and what Walt and Jesse and the rest are. If someone thinks Breaking Bad is "about" the drug game I might argue that they have missed what is actually going on in the show. Thats not an insult, so please, don't take it that way, it's just a what is. The show isn't about drugs. It's about people dealing with the tensions of life, tossed into circumstances of their own creation that causes them to deal with who they really are and what they perceive themselves to be. Lost pretended to be about that, but really it was about OMG CRAZY ISLAND! Which is fine. They are very different shows and do different things. Some shows use the stage as the setting and some use the stage as the show. Thats the major difference. Neither is "worse", they just do it differently and people will react to things that reach them.
Now, that being said, I'm not interested in arguing whether or not they are "good" or "bad" or "boring" or "not boring". It's 100% subjective to the viewer so disagree away.
And yeah, Covar, if it hasn't grabbed you yet, you probably won't like the rest of it. I would encourage you to finish the season but it doesn't sound like it's a good fit.
