DAT: As I get older I get more and more worried about stuff I'm watching having an intentional audience-pandering sexual appeal, all the while most of the characters are minors. I also increasingly realize it's not primarily appealing to horny teens of the same age range as the characters.
And, of course, this all combining with the issue of what art style is used. 15? Well you're practically indistinguishable from the character that is 35 except for maybe a height difference.
So it is surprisingly refreshing when I find some series where when the characters claim to be, say, 14, I actually go "yeah I believe that". And then the show acts cute n stuff without it feeling like it is trying to pander to creepy adults.
Like, man do people probably know how much I love maid-dragon, but there's so many times I just want to physically drag the author into an ice bath...
