Just finished watching Stellvia, another one of those really awesome badass anime that nobody has watched. D: It's from 2003 for Pete's sake and hardly anybody I know has ever even HEARD of it. It's one of the few shows that is subtle, yet straightforward; happy even though it never belittles its actually eventually serious subject matter; deeply interpersonal and yet epic, encompassing the outcomes of many characters.
Really, it's awesome. :D I'm not guaranteeing that it's necessarily in the tastes of all who read this, but you'd be very surprised as to whether you'll like it just based on its genre or appearance. You don't like sci-fi? The interpersonal aspects develop more later on than a lot of slice-of-life shows ever do, in my opinion, and displays them with much more subtlety (again, without being all artsy-fartsy pretentious :P). And you don't like the cheerful schoolkid-ness of the atmosphere you might see from the pictures and screenshots? Oh believe me, it gets beyond that later on.
I won't pretend it's an angsty show; it's not. But considering all the holy crap they end up dealing with, you'd be impressed that it isn't. And no, it doesn't fall prey to the
Angst? What Angst? trope either, faaaaaar from it. More like, deals with it more maturely than most melodramatic shows out there. Kinda like Star Trek: TNG? That similar sort of mindset/atmosphere? With a bunch of schoolkids and teenagers hanging around. XP
It's kind of nice to have a show that has faith in the strength of the human race for once. Guess you could think of it, in a way, as Gurren Lagann's tranquil, rational little sister. If you can possibly imagine such a thing. :P
