And wierdly, anime seems to be the only medium where this gets a pass. If you had 16 year olds who look (from the neck up at least) and act like pre-teens in a movie or a book it would probably get criticized as poor writing. And yes, I know that the main girl acting childish is a plot point, but very often it's simply never explained.
I remember the mother character from Hirokazu Koreeda's
Nobody Knows acting a lot like a child, despite being, horrors upon horrors, the only adult in the household...
But that was actually a very good movie.
As for this, this is probably why I considered Osamu Dezaki's take on the subject-matter more sensible: you get the impression that Misuzu is pretty childish, but it doesn't seem so mind-numbingly stupid given that she exhibits some [non-physical] traits of girls that are around her age (she's actually the one putting moves on Yukito, interestingly enough).
It's not a super-excellent film (though I find it better than Ishihara's TV series, despite the artistry not being nearly as good as Kyoto Animation's effort), but I found it interesting how little changes here and there could pretty much remove it from the realm of complete pander-tastic otaku sensibility.
Anyway, I don't know: there's a lot of animu/manga out there where they have late teens acting like children and I can only assume that this is the case mainly because it's appealing to see people who don't act their age.
(that said, it (the age and otaku audience thing) isn't always bad: I remember the robot-building discussion in the
20th Century Boys manga and it was essentially [and amusingly] a bunch of middle-aged men sitting around a table and acting like a bunch of 10-year-olds... in fact, I'm actually a big fan of Tetsuro Araki's
High School of the Dead, despite how trashy it is; Hollywood isn't actually in possession of what I consider to be this summer's hottest big-budget action extravaganza)
That said, despite being completely aware of how dumb the thing is, I still am sort of a fan of Ishihara's work...
You look at that sequence where Haruko gives Misuzu back to her real dad on the beach and it's hard not be at least interested in how well its staged; Ishihara and co are clearly pretty competent filmmakers, despite what it is that they're dabbling in...
