Like I say, it's a difficult thing to explain and a much easier thing to see. Far easier to show with someone like Tony Soprano, obviously:
The difference in his character in those two scenes is amazing, although it's not just the difference in character there but the complexity of 'intention' like I say. You can see it in the demeanour of characters and how they change as the show progresses - it's constantly happening at such a subtle and profound level. Obviously there are some events that act as triggers - the death of Pussy Bumpansiero, Furio moving back to Italy, Christopher being made, etc... but it's how these characters evolve in conjunction with the gritty realism of the setting that I'm getting at. That's what makes it so brilliant for me, because the realism of the development has to acutely map the extensive realism of the setting. It's the only show I've seen that this happens in across the board with so many of the characters.
This all being said, it wouldn't make sense for Breaking Bad to be like this; you'd lose the emphasis on the brilliance of the plot itself and on the heights that some parts of it reach. It's a different style altogether and the program would be a mish-mash in terms of what it was trying to achieve if they tried to replicate that sort of reality. Another thing; when I say that about Walter White and it being clearer about how to develop his character, I don't mean it was a simple process to turn him into an egotistical, amoral druglord either. It's just that the course is more defined with him in my opinion, with the checkpoints standing out more and providing more obvious markers for development.
I can appreciate that people would find it difficult to understand anyone that would apply this to Carmela Soprano and Christopher Moltisanti; it's only something I noticed this time round when I already knew the characters and didn't have to pay attention to the myriads of business deals, characters dipping in and out, etc... Again though, it's how elaborate their demeanour and mannerisms are. It is probably quite confusing up there when I say "a more complex array of thought and emotion", but what I mean by that is that they have to work with finer subtleties in setting and change accordingly. I should've said 'forms' instead of 'array'.
