I've heard Andor described as having the same vibe as The Mandalorian's episode "The Convert"; the one about the former Imperial scientist being rehabilitated and living in an apartment block with other former Imperials.
If so, I will like Andor. I really liked "The Convert".
The quality difference between Andor and The Mandalorian is so stark that I don't even think they are comparable. The Convert is a fine episode I guess, but next to Andor it's amateur.
Andor is prestige TV. The Mandolorian feels like a childrens show by comparison.
If you think The Convert was good, please, please watch Andor.
