Revenge of the Sith -> Andor -> Rogue One -> ANH -> ESB -> Return of the Jedi -> Obi-Wan (just for Ewan/Hayden/Vader scenes) -> Mando S1 & S2 -> TFA
that should be the rewatch order. if you wanna go real deep you can add Clone Wars (before Andor), Rebels, Bad Batch, Ahsoka to the list but thats a lot of hours
my brother also pointed out that Thrawn (from Rebels) was right all along, he wanted to build advanced tie fighters to crush resistance but Palp wanted a death star. The Rebels find out about the death star and in under 14 days its gone. 20 years of work gone in 2 weeks. Jesus Christ! Its also even more fucked up when you think about how so many planets joined the rebellion because they got fucked over in the Empire's quest to BUILD the death star.
