Iger isn't a bad CEO and he doesn't always manage from the bottom line. While he was CEO, Disney purchased Fox, Marvel, Lucasfilm and Pixar. It's hard to paint those as bad moves so far.
The numbers that Disney reports are paying customers, so Verizon doesn't have anything to do with that. Streaming is the future of media. Movie Theaters may not survive this pandemic (at least in the US). Disney will have to find a more robust means to distribute their films.
ESPN is in some trouble right now, but that is pandemic related as live sports dried up totally for a few months.
Josh D'amaro already said that the entertainment will come back in the future. Everything won't come back, but Disney isn't going to leave those theaters empty.
Disney was built on animated movies, then got in to live action movies, then got in to theme parks, then almost went bankrupt, then recovered, then bought up a lot of profitable properties......the company has evolved over time. There is no one defining aspect of Disney. The parks are still the best in the world.
