It's really fun to ask someone who was a kid after Ep I/II/III about their view of it. Lucas at several points in his career very candidly suggested Star Wars was always for kids. (It was related to criticism about Ewoks. It was related to criticism about Ewok Adventures. It was related to criticism about Star Tours. It was related to criticism about each of the Prequels and several components thereof. And so forth.) "Is it fun for a twelve year old?" was in many ways George Lucas' overriding criterion.
Of the twelve year olds I have met since Ep I/II/III, they've all generally enjoyed them.
I feel the same criteria generally applies to Ep VII/VIII/IX: for the most part 12-year olds don't see the flaws, they see the fun.
I also think history is far kinder to the prequels than contemporary opinion at the time was. (You can see it directly in some of the Ep III 20th Anniversary video essays showing up this year.)
