The worst aspect of the prequels wasn’t just the unnatural and unbelievable dialog and acting, or the fact that II and III were shot on Video instead of on film. Or the incredible bad cgi in Episode II. The total lack of verisimilitude and a used universe which the OT had in spades made everything look like a cheap 1990s computer game. There was also the moving away from established canon of the OT just because as the creator Lucas could retcon whatever he wanted. Even if 4 different special editions later the prequels and originals don’t inhabit the same mentality or continuity.

On the other hand the Disney movies are bad for lack of imagination and originality but you can have original bad like the prequels, or original bad like a sequel about Darth Maul which thankfully wasn’t made.

Safe filmaking is when you rely on callbacks and nostalgia that’s when you hire JJ Abrams. Lucas was right on the money for saying they made a film for the fans, but he could have worded it fanfilm or pastiche because that is all JJ does. The great remaker/remixer. Who saved Star Trek when it didn’t need to be saved, Saved MI when it didn’t need to be saved, and saved Star Wars when it didn’t need to be saved.
