Here it is, 4:15am and I have to be at work in less than 4 hours, but I just shotgunned the final 8 episodes straight through.
In my opinion, the ending was better than the show itself. I don't mean to denigrate the show. Overall, I'd give the show around an 8.8 out of 10. Maybe a 9.0. The ending of the show, however, I give a solid 9.7 or higher. (To me, it's virtually impossible to achieve perfection; 10.0.)
I watched seasons 1-3 three times, and season four twice. Every time I watched through the seasons, Skyler got more annoying and I realized just how much WASTED time there was on her character, especially considering how unimportant she really turned out to be. I think that many people, like myself, will find themselves fast-forwarding through a lot of the scenes with Skyler when they re-watch the series a year from now, two years from now, whenever. I'd have liked to see Jesse get killed. His main role in the entire series was to screw things up and have Walter fix them, it seems like. I'm glad Walter died, but we never really got attached to him in a personal way in terms of wanting him to stay alive because he was handed an irrefutable death sentence in season one, episode one. That kind of made the ending inevitable in terms of Walter having to die, because there was never any reason to keep him alive.
Great show, but not quite greatest of all time quality, in my opinion. I'm really glad they didn't try to stretch it out for more money, because that ruins a LOT of shows. The X-Files is my prime example of that, but there are countless others. Breaking Bad had a great run, and the ending was PRETTY much perfect. Certainly one could not reasonably expect more, in my opinion.
