D'Amaro, like Iger, is very effective at controlling his image. That's why he is the choice. I continue to believe that Chapek's term as CEO was essentially as an intentional fall guy - they put him in charge, let him make a bunch of unpopular (but profitable) business decisions, then gave him his golden parachute. Did they roll those decisions back? Nope.
While I love the Parks, you can't make a coherent argument that things have been getting better. Like many other services and products in the world, prices are going up and quality is trending down. Pay more & get less is the modern way for corporations to make money, and it's sad to see Disney find themselves there as well.
I have no opinion of D'Amaro one way or the other, really. As said above, meet the new boss, same as the old boss. Unless they start properly staffing the parks and maintenance teams (but that would eat into profits), I'm going to be grumpy.
