I agree Rogue One best movie since the original trilogy. I like Return of the Jedi so I'll say it's the best SW movie since that. Andor written and created by the guy who co-wrote that film.
I just started watching Andor. So far it's very good and very different. A character study, the characters are very well written as is the dialogue and acting. A lot more nuance in this show, explaining motivations by the rebels.
