it's less noticeable in person where you don't have the most 'equals sign letter D' angle on it because of height of that area of the fascia and the fact that the 'nose' of the car above it kind of juts out (on my 3, at least. some of the others are a little more rounded).
mines also a dark gray color, so it blends with the plastic. overall i like the look and embrace the insanity of its grin (helps with mazda's status of being the goofiest but also awesomest japanese carmaker). but it's accentuated too much on some cars. fog lights don't help, and the miata with the chrome trim around the 'mouth' is pretty aweful (edit: haha, meant 'awful.' freudian slip?).
