This is why I never believe in the talk of "superhero fatigue".
As we've seen with the MCU, the tones of the movies can be completely different from movie to movie. As we've seen just within the past year movies like Black Panther and Wonder Woman, which feature both under-represented on-screen genders and races in lead roles, have done amazingly well at the box office and smashed Hollywood stereotypes.
I do think Disney trying to bring Star Wars to this scale will be what ultimately breaks it though. There's so much content to draw from with comics where as with Star Wars, they're mostly just hiring people to do fan-fiction movies that are within the canon.
