Chapek made a lot of poor decisions and should never have been CEO. The parks business was thriving in spite of Chapek, not because of him. That said, I have nothing but good things to say about the decisions Disney has made since Iger returned, especially regarding the return of creative control and accountability (will take a few years to produce result.)
Disney’s relative weakness at the moment is primarily due to disruption across the entire media industry. Most of Disney‘s competitors are struggling much more than they are. I do think Disney is in a really strong position to weather the disruption and come out as the dominant player in the new media landscape.
