Asses

Milo Manara's alternate cover for a Spider-woman comic. Very good in my opinion. The first thing that struck me was how pleasantly erotic it was. But the character has this strange, alien face which makes it that bit uncomfortable to look at.
As always (and intended by Marvel's marketing department, I'm sure) it brought out an almost universal cry of disgust on websites and their comment sections.
What struck me most of all was how many people started criticizing the anatomical mistakes in the art. Scrutinizing every inch of it. The reason behind this seems to be that it's not enough to admit having a problem with a sexually exciting super heroine. The discomfort ,and even anger, has to be expressed in a less personal manner.
What quite a few of these critics lose sight of at this point is that a comic book cover is meant for direct visual impact. It's not wall-art. Although some of Milo Manara's work certainly has the added bonus of working like that as well.
Many really good, classic comic book covers ar anatomically a complete mess. McFarlane, Kirby etc. Their work isn't about being perfect classic anatomy. It's about the viewer going 'Wow! Cool!'. And most people understand this. Unless there is this pesky erotic element of course.
