I’m not here to argue about the characters of R1. My problem was with your assertion that it “didn’t even attmept” to be character-driven. You presented ‘not being character-driven’ as a criticism in itself and I think that’s not valid. Movies can be good, without being character-driven.
Sure, you can say you find the story boring and making the movie more character-driven would improve it. That’s fine. And you can say you find the characters bland, so they should be improved, and that’s fine, too. I disagree with that, but at least, these are valid ways to criticise the movie.
