Well, it's also a sane business practice. When you have limited abilities to predict what is going to be successful, you are tempted to use the schemes that worked well in the past. You take the ingredients that are known, combine them using aesthetic means that are attractive in a given period, and promote it well. In this way you minimize the chances of failure. Experimenting with novel things is not a safe strategy when you repeatedly invest millions, and your way of doing it works. That's why you have, for example, a remake of the Beauty and the Beast (and many other), both by Disney. They know the target group will go and watch it and enjoy anyway.
