I'm going to go ahead and say it:
Breaking Bad's finale was better than sopranos, but Sopranos was still the superior show
No doubt The Sopranos is easily in the top 5 shows of all time, and without the Sopranos, there may have been no Breaking Bad. The Sopranos was groundbreaking, and changed forever the landscape of dramatic television.
But, many have said The Sopranos went a season or two too long. Some even say it was all downhill after the first 2 seasons. Breaking Bad, by comparison, has been almost universally praised for being relentlessly riveting for every single episode of every season.
In terms of pure storytelling, Breaking Bad had an almost perfect arc. Its undiluted clarity of vision and purpose for the entire series makes The Sopranos look like a wandering mess. BB had a much smaller, tighter cast. Zero superfluous characters. There were no filler subplots. Every efficienct and purposeful minute of each episode served solely to drive the story to its predetermined end.
And therein is my only criticism of the show. At times throughout the 5 seasons, it seemed to me as if the writing had to bend to the story; the framework of the entire show was already complete, and was built upon by the writers as the show progressed.
I did not believe in tonight's episode, for example, that Jack would pause Walt's demise merely because he was insulted by Walt's insinuation that Jack and Jesse were partners. But the story obviously needed that pause for the gun in Walt's car to be deployed, because the gun was part of the story before the writers worked out exactly how he would get to use it. So the writing bowed to the framework, because the framework was rigid and the writing had to follow it.
The Sopranos on the other hand, meandered, sometimes rather aimlessly, not unlike its predecessor, The Wire. The writers knew Tony inside and out, and had a blast writing for him, but ultimately, they didn't have as nearly a developed story to tell. While the story of Breaking Bad took the path of an unfaltering arrow, shot skyward then plummeting downward, The Sopranos' arrow dipped, dove, rose, veered, and ultimately, in the last episode, simply faded from view.
The Sopranos played out much like a long big budget soap opera; Breaking Bad more like a finely tuned 3 act play.
I do believe Breaking Bad owes much of its success to The Sopranos, but like many a son of a great father, Breaking Bad took what it learned from The Sopranos to the next level, and beyond, and managed to accomplish things The Sopranos never achieved.
And the show that comes from the groundwork laid down by both of these fine series will undoubtedly be even better.
