The callbacks to earlier episodes and characters served a purpose. Saul's time machine question means he had been regretting his bad choices--even years before meeting Walter White.
Confessing to EVERYTHING not only saved Kim, but means he finally made a right choice. And he ended up in a prison where he's a celebrity to the other inmates, and he gets to continue practicing his Cinnabon skills.
Weak, weak, weak. The show took a terrible nose dive with the Salamancas gone. Cop out ending. The end of Breaking Bad was fantastic. This, weak, weak, weak.
When Kim Went to see him and mentioned that her law license was still active in NM, I thought she was going to offer to represent him in appeals.
We noticed that the smoking scene was like the parking garage in the beginning.
