Even though it was the point I got closest to guessing, I am not really happy with the money issue. When Gretchen and Elliot hand over a 9 million trust fund, Skyler and Walter Jr. would have to be pretty thick to not connect the dots.
But then I'm happy that they wrapped it up... they could have easily filled a season with the potential plot between hank's death and Felina, and with enough time they could have come up with a more satisfying story but it's ok.
As much as I wanted a 9 hour finale, in the grand scheme of things I can accept their decision.
