I'm probably pretty alone here, but I don't have toooooo much of a problem with the redesigns. They're exaggerated to a point well beyond silliness, but shouldn't we expect individuals to tailor their fashion around their personalities? In the modern world we have jocks, emos, goths, hipsters, rastafarians, preps, and countless other groups of like-minded people all easily distinguished by their fashion. Is it so unlikely that Donatello would like the look of some steampunk goggles? Or that Raph would wear some badass shades? After all, not only are they part of the modern day, not only do they live in a city full of diversity, but they're TEENAGERS! If anything the redesigns make MORE sense than their traditional look, despite the aforementioned silliness.
