Basically this. At 9pm I sat and really contemplated watching baseball, football, or Walking Dead. And I don't even like baseball. When new episodes of Breaking Bad or Mad Men are on, the world shuts down for an hour. I'm sticking with it, though. It's decent enough television and I've been watching since day one, episode one, so I feel some obligation to finish it out.
Exactly how I felt. It's still a good show, but it's losing me. I was more excited to watch Sopranos reruns on HBOGo after it finished.
