Though I do believe a balance has to be struck between plot moment and characters moments.
I can watch a show with terrible plot but excelent characters,
I cannot watch a show with great plot but uninteresting characters.
So I tend to believe character > plot any day of the week... But having both is what makes it really fun.
A good set of characters can only carry a story so far before their poor little backs break.
I also find it very boring when stories focus a whole lot on certain plots, particularly the political and or 'demon king' stuff. like it's ok to have that as a backdrop for the characters... But i've seen to many times
the empire of darkness vs the kingdom of light,
or the red army vs blue army,
or the widely diverse set of culturaly stereotypical nations colored after the same basic primary colors and representing real life cultures preparing for war for any petty reason.
I get why people do that, but it never feels fresh or interesting,
Regardless, I'm digressing...
Secondly, I do not believe wether the character is passive or active in the plot is really the main factor. It's all about framing... A passive character can be so to emphasize how desentized they are, how they feel like they have no hope or desire to fight back and instead just experience everything as if it didn't matter, and it can often create dramatic tension for the moments they do decide to act.
Expo-Dump characters can go die in a fire though. Especially the annoying and useless sidekick variety.
