I think it’s partially because the “MCU” technically started outside of Disney, and was purchased, whereas all of the new Star Wars content (barring the prequels) has been under Disney’s wing. Also, they are starting to wreck the MCU as well.It's odd to me that people are more than willing to voice disdain for Disney's rather than Lucasfilm for the failures of managing the SW franchise, but will generally heap praise on Marvel, not Disney for the success of that one.
Actually, when Disney bought SW and a bunch of people jumped on the bandwagon saying “it’ll be bad because Disney is making it”, I defended Disney using Marvel as an example of them being capable of delivering. Sad times that I have to go back on my words.
Edit: not to mention, when Disney bought Marvel, it came with a strong leader with a vision, Kevin Feige. The foundation had been laid and the leader knew how to lead. There was no “first new SW film” like Iron Man to set the stage well before the suits got involved, and Kathleen Kennedy is a terrible leader. She might be a good producer in other aspects, I don’t know, but she has no idea about story, planning, audience engagement, reading the room, not putting her foot in her mouth, standing up to Bob Iger and his Disney cronies, etc.
