I don't think they could have ended it any other way, however, while I am completely satisfied and, really, happy with the ending there's just this feeling of want. I think it may be due to that I really enjoyed the show. Maybe that I grew attached to Walt and Jesse, but I wanted a better ending scene than Walt, on the ground, dead. I get that it's a metaphor, him dying in the meth lab that was the last place to cook his meth, it isn't lost on me.
I would've liked a funeral ending. Or a burial ending of some nature. Walt being put into the ground by some nameless guy while no one is around to see him go. Or a news report talking about the death of a drug kingpin. The ending was bad, in my eyes, because it gave too much closure. There's nothing else. If it was a news report and the screen turned off then we'd have that, "who was that watching the news?" Skylar, Flynn, maybe even Jesse. I'd like it if it was Jesse, seeing that big, bag devil in his life finally in the ground.
Remind, I'm not knocking the ending. It was absolutely perfect in its toned down state. I just didn't want it to be so closed at the end where I know everything that has happened.
