And it's not just started at Days, even KH1 already shows the idea of suicide in other to save another. So yes, while Disney wouldn't show explicit gore or sex, psychological horror/ not-so-to-the-face mature content is still a fair game for Disney, As you say, 0.2 is a perfect example of how it's not particularly gory but is clearly psychological horror, like, okay, darksides are not as scary as Resident Evil mutants. But the idea of alone in the place where there is veeeerrry minimum light, where time doesn't pass, and then your greatest fear takes form of a clone of you and gaslights you using said fears in hopes you give in/to replace you? that's quality psychological horror there, it's basically pandora hearts meets persona. so no it's not childish at all, but thing is, some edgelords precisely think if there is no explicit gore or sex it's not mature, when mature is more than that, but yeah, emphasis on edgelords-and thus, they can't accept the fact disney isn't childish, for they don't want to admit disney work can be mature without catering to their edgy wants.
