I would hesitate and even admonish the use of the word lower expectations. This is 2017, we as a people have not remained stagnant since AA's were first introduced, but, we have become more tech savvy and therefore have made changes in how we present our entertainment. In 1955, basically through 2000 the AA's were the technology of today and the future. Robots and all. Today so much can be accomplish via screens that couldn't be back then and it is the way of today. Keeping AA's around is a good thing, but, putting down current technology just because it is different then what we were accustomed to is very short sighted indeed.
What we have to do is adjust our expectations and allow it to capture our imaginations just like AA's did back then. What I have read about Walt Disney and his constant desire to change, update and expand, he would have completely embraced the new technology and tried to find new and inventive ways to use it to tell his stories.
