I'm disappointed I missed some of the streaming debates from earlier (damn you sleep!), but I guess the one thing that does make me concerned about Disney+ is the potential churn factor. I'm hyped for a couple shows, but most of the originals don't scream must-sees, and I feel like after I marathon through all the Pixar and Star Wars stuff, and watch some childhood classics enough times, I'll just get bored. But then again, there's still the Fox content to come after their HBO deal wraps up, as well as the other Marvel stuff still going through other licensing rights, and Hulu is included in a bundle, so I guess I'm complaining over nothing.
Should still be more successful than what Apple is doing. They're asking $10 a month for nothing but original content that may or may not be good, while Disney+ is offering $7 a month for all the Pixar movies, every Simpsons episode, all the Star Wars movies, and all the Disney Channel movies. Even if all the originals suck, you've got enough quality content to work with.
