Andor (at least Season 1) is very slow, boring, suffers from "static heads talking at each other" cinematography of modern movies [1], main character is just not a great actor.
All that said, it's definitely worth a watch:
- most, if not all, major characters (apart from the protagonist) are very compelling, chew through every scene they are in, and are great matches for their parts
- Empire is finally shown as a proper huge, relentless, uncaring bureaucratic machine it must have been. Run mostly by efficient ruthless bureaucrats.
- Rebels are not angels, are not a single conformist mass of do-gooders
- The dialog is mostly great
It's a much better show than Mandalorian. It's arguably the best Star Wars after the original trilogy.
[1] Most modern productions are incapable of shooting "walking and talking at the same time". Most modern movies and TV shows have actors placed against each other rigidly, with not a hint of motion, as they say their lines at each other
