Yeah, if you just look at the overnight numbers, it's pretty underwhelming. It's one of AMC's lowest performing shows only beating The Son, Humans, (co-developed with Channel 4), Turn (ending after this season), and Halt and Catch Fire (also ending), and it's ratings are lower than last season. But when you look at Live +3 and +7, it's a completely different picture. Once you take those into consideration, BCS is one of the most watched shows currently airing on cable. Its ratings are also higher than Breaking Bad ever had until its final season. I'd be really surprised if AMC didn't bring it back.
I didn't really see that as all that bad. Jimmy really doesn't realize how overworked Kim is. He still thought Mesa Verde was the only thing she was working on and was surprised when she had something else, but when he tried to ask her about it, she just brushed him off and told him she'd talk to him about it later. Kim has also had a tendency to want to do things on her own and doesn't often ask for help when she needs it. Not that I'm dismissing Jimmy being self-absorbed over his win, but I didn't really see it as particularly egregious, nor do I think he bares much responsibility for Kim's crash.
