You couldn’t be more wrong about everything.Nope.
You're looking for tonal freedom and variety in the wrong place if you expect Star Wars to be like the MCU.
Star Wars is, has always been, and always will be a Children's Myth-based Space Fantasy done in the style of a 1940s Film Serial. That is never going to change... not because of "familiarity", but because doing so would cause the franchise to cease being itself.
