I suspect some people have decided that Medaka Box is a deconstruction of all things shounen and then get upset when certain parts don't seem to match up their idea of what a deconstruction should be. I personally think MB has fun with shounen tropes, while sometimes containing deconstructive elements (particularly the characters of Kumagawa and Ajimu, though not always). But! I don't
need it to be or not be a deconstruction to enjoy it! Even when I don't always
like the direction of the manga, it's still damn entertaining every week. And thus, I sincerely enjoy it. /endrant
