MCU fans don't have that 40 year old servitude to adhere to. They said right off the bat "Nope, we're doing our own thing, come along or don't"
I think Star Wars fans are their own worst enemy. They demand fealty to ideas/tropes/storytelling that has always held the series back. They complain if they aren't there, they complain if they're there and nothing is new, and they complain when they get bold, new takes.
The entire recent trilogy of Star Wars is a microcosm of those problems. Only the Mandalorian has risen above those problems and, surprise, one of the MCU's main guys is behind it.
