Most of the movies seems more like a collection of very cool and memorable scenes thrown together without context.
Think about how Lucas himself has fared in the court of public opinion/fandom. He should be a god, based on the original trilogy, but he's treated in general more like kind of a disfunctional uncle at best. There's not much for that downfall to be caused by except for the prequels (and some mosly dumb changes to the originals over the years on rereleases).
The Disney ones, at least for me, they're well acted, fun, the fight scenes are good, they have good story beats, and some interesting characters, etc. The overall plot is certainly a mess, but to me that's at least less of a problem than everything wrong with the prequels.
The thing with fans is they either gushingly like whatever is marketing to them or they move on to something else. So I would expect fans, if asked at a Star Wars convention, to say they loved the prequels and loved the Disney movies. If that wasn't the case they wouldn't be at the convention.
