Okay so this adds absolutely nothing to Rogue One and is completely pointless.
The entire story is driven by Luthen and Dedra (the only interesting character)
Mon Mothma doesn't actually do anything for the Rebellion except donate some credits, and then gets blackmailed into selling off her daughter, but it's okay because it's totally a tradition on their world and her daughter is into it because reasons
Syril's character becomes irrelevant for the whole second season
Dedra's bad ending is hamfisted in at the last second
Not a single established alien race from the OT or the Prequels appear with the sole exception of Admiral Raddus, every other alien that appears looks like a scrotum
The Rebels are now morally grey IRA/Hamas types, and so the Empire has to be portrayed as even worse
This is accomplished by adding in an attempted rape scene
The architecture on Coruscant looks like shit and doesn't match previous depictions
Everything is constantly wet
And worst of all
Andor is completely irrelevant to the story and is barely a character
There are some good things about the series, the acting is solid pretty much across the board, Dedra's plotline is the best part of the show, the prison episodes in season 1 were the highlight of that whole season, Kleya doing spy shit in the hospital was fun to watch, and K2 acting like a Terminator was cool.
If this is what you consider "the best Star Wars" then you obviously don't like Star Wars.
I consider the Filoni Disney shows are shit too (with the exception of Mando S1) if you think that's what this is about. Andor is just shit and Gilroy clearly has nothing but contempt for the Star Wars franchise.
