My wife and I are currently going through Breaking Bad doing exactly the same thing. We've lost all patience with the main protagonists, the most promisingly healthy looking relationship in it died rather dramatically, and now the bulk of the drama is based on the main characters' poor, not necessarily forced, choices and even worse communication - and everything we think is wrong with the American system and attitudes. Maybe that's the point. But when the only character we're left with real respect for is the top villain, for his attention to detail, it's a bit odd.
