It was clear that Gilligan didn’t want this to be the Sopranos, and he was refreshingly critical of such an ending in the aftershow (though, he did diplomatically backtrack a moment later; it’s amazing how there is a blue wall in every field). Everything was best tied in a perfect bow and handed to the audience on a silver platter. I’m okay with that. For me, it matched the show. Breaking Bad was solid entertainment, but that\'s all it was. After each episode ended, I didn’t think about it again until the next episode. A clean –an OCD cleaned– ending seems very appropriate. Other than conversationally, I’ll never think about it again, and Gilligan made that easy.
But there are the 55 hours or bonus stuff on the final DVD set.
I liked this write-up on the Marty Robbins\' song:
I think that Felina is the meth lab itself. Toward the end of the Marty Robbins song, the cowboy is shot in the side (“Something is dreadfully wrong for I feel/A deep burning pain in my side) and Walt was shot in the side. The last verse of the song is: “From out of nowhere Felina has found me / Kissing my cheek as she kneels by my side / Cradled by two loving arms that I’ll die for / One little kiss and Felina, good-bye.” The “two loving arms that he’ll die for” are the walls of the lab that he has just walked into, and that “one little kiss” would be his touching that piece of equipment before dying.
It's dead and over when close enough is good enough.
