I heard Monsters University was good, but haven’t seen it.
Surely that list must be missing a lot of movies, I’m sure we’ve had more prequels than that.
The ones that are the best mostly seem to be very loose prequels.
(Good, Bad & Ugly, Temple of Doom - for these ones being prequels or not is effectively irrelevant. Fast & Furiouses - for this series the timeline is so loose, and they aren’t really prequels except in terms of one or two specific events.
Spartacus: Gods of the Arena, Rogue One - these ones basically focus on totally new characters and only time in in terms of side characters or ultimate events being known)
Godfather 2 and Infernal Affairs 2 are much more direct sequels, although GF2’s split timeline means its also a sequel. IA2 isn’t as good as the original, and suffers from boy band casting and ridiculous coincidences that tend to affect prequels, but it still manages to be ok).
So, yeah, prequels that take a very loose approach to things seem to work much better.
With Star Wars particularly, it’s weird that the things that the first trilogy pulled off so spectacularly well kind of became its downfall in terms of prequels.
IMHO the world building of the first trilogy is amazing, partly because it manages to fill out and entire universe of back story by just throwing out oblique references to things like “the kessel run” and “the clone wars” etc. Your imagination fills in the rest.
But then that very fact is what created legions of fans desperate to know more, and that’s why we’ve ended up with 5 prequels and only 2 sequels. And it has almost universally turned out to be a bad idea to fill in those details as they haven’t ever lived up to our imaginations.
(Rogue One being the exception, but also the one most loosely tied in)
