Rogue One was great. The moment I saw Jyn being transported in Jaggurnought, I was sold. The Star Wars universe, from the original triology over the Clone Wars to the extended universe from the days of Westend Games, has so much stuff to work with. Stuff, that is now free to use since it is not canon anymore. The sequel triology did nothing of the sort, insetad it took the idea of a reborn Emperor, IMHO among the worst ideas of the Legebds EU, and made somehow even worse.
When the hinted at a fleet of hidden star destroyers in Rise of Skywalker, I so hoped they would steal some elements of the Katana-fleet story arch. But nope. Funny how all the series set after Endor do their utmost to ignore the sequel movies, at least it feels like that to me.
Fo rTgrawn so, they could have skippes the zombie stormtrooper part. Star Wars zombies were a bad idea when introduced in that book about an infested star destroyer, written at the hight of the pop culture zombie craze, and are an element the new canon could have well lived without. After all, Thrawns thing in Timothy Zahns book triology was cloned soldiers. But we will see how that story goes, Thrawn is bavk, and I'm all for it!
