I had a million thoughts racing during the really slow developing parts, the long takes that showed emotion etc., and I was thinking just now that it's intentional, to mirror all the stuff going through Walt's head and to let all of the small implications set in while they're happening. The art direction of the whole show is just absolutely top notch. When Walt is watching Jr walk in to the house, and then he turns and walks away and his silhouette is obscured against the glass and everything slows down, and they're obviously spelling out for you this is the last time he will see anyone in his family... just remarkably powerful stuff.
Walt is no hero, he doesn't ultimately deserved to be rooted for in hardly any capacity, and the way Jesse doesn't allow him to go out on his own terms right away is a great show of that. But the series shows top to bottom that even the most despicable characters are people too, with complex motivations, fears, and emotions.
I don't need to have a conversation just yet about where the show ranks in all time television, but it's an example of a series that continued to set the bar higher and higher for itself, and never failed to meet its own expectations anf conditions, and for that it has to be celebrated.
