Andor was a very well-written series addressing some serious (and timely) themes that just happened to be set in the SW universe. That give at a chance at broader appeal, and the almost complete lack of the mythology, and relatively little tech also helped it to be more approachable and relatable to the uninitiated.
Andor's story in the series, and the film, is easily one of my favorite, if not the favorite part of SW for me, especially given the current state of the franchise.
Luke ending up as an angry hermit, and Han Solo, of all people, effectively meeting his end by being shivved by his and Leia's emo son? I would have loved to be a fly on the wall in the meeting when that pitch was made.
It might have seemed like a good idea to some people at time, but to me, that is probably the biggest crime, so to speak, of the sequel trilogy, having those characters meet fates I'd neither imagined, nor ever hoped that they would.
