I believe I may have said this in the past, but here's the deal...
To every story, there is always three takes on the story: person A's take, person B's take, and what actually happened. What person A and person B often do is tell their story so that they come out as either the victims or the victors of the situation, but the events that actually happened are either hidden by those same people, or no one can't truly recall it. What I am getting at is that we can raise Brenda Chapman as some sort of heroine that spoke against the evils of Pixar, or we can say that Pixar was the victim of an artist that refused to cooperate and was too enamored by her own story to do anything about it, the reality of the situation is that none of us were there to see what actually happened, and thus I think it is unfair to damn either Pixar or Brenda Chapman based on just a few comments and interviews. I mean, for all we know, Chapman would be playing herself to be a big victim so that people pity her and thus she gets more work, or Pixar's reluctance to say anything could confirm the ill wills of the creative process. But until someone comes out and says "THIS IS WHAT REALLY HAPPENED", to damn and praise one or the other is silly as this point.
Also, regarding the insults and comments towards John Lasseter, let it be clear that within the company he is just ONE MAN following the indications and rules of other men, men with far more power and control over the assets of the company. To fully blame him of the decisions THE COMPANY has taken as of late is unfair and childish, to be honest. Lasseter may have a lot of control at the company, but that still doesn't compare to what the overall company has to say and do on the matter. If the company said that 2D films are not profitable and see a brighter future in computer animation, what can Lasseter do about it? Clearly, he tried his hardest to bring Disney back from the brink and create movies that were both classic and progressive in their execution, and if the company did not see it as wise way to keep the company afloat, then sacrifices had to be made. It sucks that a lot of people lost their jobs and that we won't see any 2D films in a while, but that is what happens when not just the animation industry changes but the audience as well.
I mean, people seem to forget that back in the 70s and 80s, when Walt Disney had passed away, Disney was operating on the "What would Walt do?" belief that barely kept the company alive. Now, had the company be re-invigorated with a change of plans, new concepts and ideas, we wouldn't be talking about the golden age, and how today's Disney should be emulating THAT Disney. In short, the reason we even have a golden age to reminisce about was because Disney needed to change and keep up with the demands and needs of the audience, and it is clear that right now Disney is just trying to follow up on the trends that interest today's audience, and considering the success of their most recent outings, it seems that their efforts are paying up. Not to mention that they are now fighting against other companies for the same audience, so they have to make changes and sacrifices in order to stay relevant in the grand scheme of things.
So we can all damn Lasseter, wish him all the STDs in the world, wish him misfortune and bad luck to kingdom come, that won't change the fact that he is just one man in a larger than life company that is trying to stay relevant with the needs of the modern audience.
Either realize that sooner, or just keep throwing temper tantrums like this...
