I reckon Eps I-III are best consigned to history. III was probably the best of a bad bunch, but it does contain some of the most unintentionally hilarious moments of any movie I've seen. Like this bit, for instance:
https://youtu.be/tv666PtpD_MPlus, you have the whole transformation into Darth Vader thing, which was probably the highlight of the movie, but then what does he do? Says "Noooooo", force-crushes some medical droids and then stands on the bridge of a star destroyer and crosses his arms. Hardly menacing..
Growing up with Star Wars, part of the fun was the mystery of the parts that weren't shown on screen. You didn't know where Darth Vader came from, you just knew he was there on screen, kicking ass. The rest could be made up in your imagination.
That's what worries me about the upcoming Han Solo spin off. Do we really want to see a baby Han take his first steps? Or a spotty, teenaged Han whining about why none of the girls will talk to him? I don't think so...
