If a shounen isn't allowed to be about the fundamental fight between good and evil, with said fights being carried out through the proxy of colorfully decorated personalities, then at what point does it cease to make sense for it to even be made at all? Or better yet, why bother to scrutinize it for doing what that genre has been predicated on since its inception? At what point does valid criticism capsize towards the side of pointless nitpicking? You won't always discredit comedies for having situational humor nor will you shame an action movie for delivering on its promise of cool fights and chase scenes. a shounen in such restrictive terms, to begin with. But if you did decide to adopt that approach, that then calls into question the very essence of critiquing And if you were to choose that stance, defendants would be hard-pressed to argue against it. Or something to the effect of its story being recycled. To make broad statements about the characters themselves being repackaged personalities with only a fresh coat of paint and appearance to their name.
It's easy to point the finger at Boku No Hero Academia and label it as just one and the same as any other shounen that populates the medium. Minor plotting events will be addressed and forwarned in advance.
