To be honest Star Wars has never been about great directors. It's pulp. It's meant to be light and fun and inventive.
The real issue with all the prequels and sequels is that a tossed-off "planetary romance" plotline written in a fever dream by George Lucas doesn't really have the fictional scaffolding to support a dynasty saga and a galactic empire of self-consistent world building, ie what you need for a major "cinematic universe".
The new aliens and settings that have begun leaking for the upcoming Han Solo film sound like rubbish. They've been missing way more often than hitting adding to the "property" of the Star Wars universe since ROTJ came out the first time around.
