Yeah, good luck watching those on your phone or tablet, which is how many people, especially kids, consume content.
Maybe they have the discs, maybe they don’t...Disney obviously knows better and has bet big on this. They certainly don’t have discs for Mandalorian and something like 30 seasons of the Simpsons and all of it in one easy interface ready to watch on any device. Preliminary numbers of nearly 30M in 10wks confirms it‘s a blowout success.
Disney has limitless content...Avengers was one example. Make a list of all the content Disney owns and let me know when you run out of ink.
If content is your concern, that’s the wrong concern, IMO.
Netflix should be the one worried about content.
While Netflix is in decline, the content is superior to Disney+. Let's examine. Disney+ content is all the stuff we already seen. New content is minimal and bland. Yes, the Mandalorian is "ok" but the plot is thin and with 8 episodes at 30-40 minutes a pop, leaves a lot to be desired.
Netflix releases new content for all audiences frequently, some are duds while others are hits. The key here is new content for all audiences. How many times are you going to rewatch The Last Jedi? Reruns get old quick. Disney has a long way to go.
