Andor and Rogue One are better prequels than the prequel trilogy in that they better match the tone of the original Star Wars and do a better job filling in the parts of the back story viewers care about.
How did the Rebellion start? How was it organized? What led to building the Death Star? How did they get the plans to give to Leia to give to Luke?
The only part of the prequel trilogy relevant to the story in A New Hope is the final battle between Anakin and Obi Wan.
If the prequels taught me anything, it's that these questions are usually better left unanswered.
What's cool about the Force isn't the mechanics of how it works. What's cool about the Force is that it's a mystical thing that's everywhere, binding all living things together.
And we honestly don't need to know how the Rebellion started. It doesn't matter! They are the good guys, and they are messy but kind and loving and cool and they are rebelling against the cold and mean (but also sometimes cool) bad guys. In fact, the more dumb shit I know about them the less I can project myself onto them and see myself in their eyes. Because I have rebelled against mean authoritarian shit before, or at least dreamed of it, but I have never been involved with trade disputes or galactic senates or weird old religions.
This is true IMO 99.99% of the time.
Shockingly to me, Rogue One and Andor are so well done that they are exceptions to the rule.
