I actually think Andor has a great premise. You have a character that is not that high in the power or popularity tier levels but that has shown hints of depth and a nuanced morality, this makes it a great protagonist for a smaller-scale setting and stakes that still could make for an engaging plot and worldbuilding thanks to the spy aspect. Hopefully they will tackle Cassian’s Separatist past, that could make him stand out even more (since the canon has barely delved into the benevolent people on the Confederacy’s side). I really like the Star Wars underworld as a setting, because it offers a lot of opportunities to reach further in regards of what the galaxy has to offer in regards to tone, locations and setpieces.
