We see what we want to see.
So, it's no surprise that members of 12-step programs saw in the film "Saving Mr. Banks" a morality tale about the destructiveness of alcoholism. The father goes from being a charmer to a menace in the workplace and destructive force in the lives of his wife and children. The wife attempts suicide. The first-born daughter is an emotional mess, until Walt Disney liberates her from her self shut-down.
However, there's much more to see than that in "Saving Mr. Banks." For example, it's an accurate depiction of how a creative team, whose members trust their instincts and each other, can produce amazing content. Also, there are the selling skills of Disney. He knows how to close a deal, even amidst obstacles. Another reason for ponying up the price of admission is to bear witness to the potential power (mirror neurons) one human being can have on another. The Disney driver and Mrs. Travis establish a connection. That breaks them open to new ways to frame their individual emotional ordeals. And then begin healing.
