Prequels are weird, not bad. What people criticize about them can be said about Babylon V even more, but I haven’t seen many people calling it a bad show.
I’m not impartial - I’ve grown on “prequel EU” as much as on “original EU”, but started with the former, trying to really interpret Jedi philosophy and such. My brain is not agile enough to separate pieces of EU and their closest movies by now.
But there’s that moment that with prequels the EU and the movies were being created simultaneously, there were official layers of canon and Lucas himself would even refer to EU. So - I don’t know. Maybe as self-contained movies they are bad. Their aesthetic gave me a lot, their emotion feels more real than Andor’s second season (its first season is better though), their music.
Yeah, well, your first paragraph reads so impressed that I’m certain you haven’t read at least X-Wing books (all my favorite, Stackpole’s ones are sometimes too comfortable, Allston’s ones are sometimes cringe in technical and logical regards), the Thrawn trilogy (the part of the EU usually recommended first) and the Death Star (to compare the old and the new). I liked Andor, once again, and I would like it without Disney’s dark years, but those things were very good and deep too.
To each their own.
