No way. 9 episodes is overkill for the amount of stuff they've got to clear up, which is basically the Hank, Jesse, Skylar and kids triangle. I'm pretty sure you could dedicate an episode to each one and it'd be enough.
The show needs to conclude, and I'm glad it's doing it in the next 9 episodes. The characters are done for, they've run out of juice, and they're ready to die out (not literally). That's not a criticism, if anything it's a compliment, but they've just run their course and finished their journey.
Walt's batshit insane.
Skylar's done with any sort of relationship.
Jesse has finished making Meth.
Hank has climbed to the top of his profession.
All we need are revelations, reactions and my overall
guess at the conclusion:
