I understand the logic he's following by saying that. But as someone who grew up with lots of Japanese games and anime, that argument doesn't work for me at all.
Sex appeal in many forms in Japanese media is something that is not even a problem, the problem mainly comes from either cultural differences or a lack from someone to make the effort to view things in a open-minded manner.
Then again, a few that has complained about Bayonetta in the past do it out of the insecurities each of those people have/had at the time. Which, at the end of the day, ends up in a discussion where there's much ado about nothing and Bayo keeps being as sexy and fun as it has ever been.
Games get docked for shitty voice acting, poor music, bad visuals and so forth, so why not something that is both consistent and [deemed] tacky that's getting in the way of the person's overall experience?
