The look and feel of Rogue One translated over to Andor, but this is surface level stuff. For it to work the kind of characterisation we have now would have be included in the movie. Beyond it not working as a prequel and having too many pointless fan service characters, the reason I don’t like Rogue One is the heroes are nothing but cardboard cut outs. Somewhere there are deleted scenes with Saw and child Jyn that maybe fix this? But it should have been the focus, two fold, with Jyn’s search for a father figure and the mystical Jedha stuff. So I care when she dies and when the planet dies.
However. This is my take, not the general consensus. I got the impression that most people love Rogue One. So it’s failure to find an audience is odd. Particularly when certain SW fans really want it all to be take so seriously. Which means the problem is probably the same fan service being missing. I guarantee people would watch if Darth Vader and Palpatine were shown. Which is my concern for Season 2 and where it could start to crumble.
