Ignoring all the 'trash' anime that come out like clockwork, what makes it better than the handful of other "special" shows people point to regularly as life-changing? I can't think of anything beyond "well, it's personal, and reached me personally in a way those others didn't." So really the ratio is much better than that, when you take into account the many other shows that are apart from the herd, but that have that magic effect for other people.
But even if it were that bad, wouldn't it be better to say that the one exception justifies the medium? To have one thing you can forever point to and say, "this - THIS is why we need these dumb foreign cartoons. It's not a lost cause."
