Here's the correct answer on the Star Wars prequels.
They're not good movies. They're not super enjoyable to watch. They have some quite bad elements.
But they exist in a very good universe that feels full of stories and potential. They're good world building. The original movies takes place on the fringe, you never really see the galaxy they're fighting over. The prequel galaxy is dense, alive, populated. You can imagine being a jedi in it, a sith, a merchant, a simple man.
And everything good after, clone wars, andor, rogue one, feels like its in that rich full universe the prequels made and set the tone of. The prequels weren't good movies but they were good for *star wars*. They made more stories possible and appealing to tell than before.
The sequels were also bad movies but they were also bad for star wars. They fled the rich galaxy back to the fringes, killed off characters and whole political systems in bulk, ensured no post empire pre sequel politics could be interesting because we know it utterly fails immediately, ensured no new jedi order story would be interesting because it utterly fails immediately, and then left a bunch of new threads no one cares to follow. The movies arent that much less enjoyable than the pretty bad prequels. But their impact on the range and attractiveness of potential stories was the opposite, shrinking the pool not widening it.
