Comics and Such

So I just got a slough of new graphic novels the other day, and I'm just wondering, why is it that comic book characters are always so physically exaggerated? I personally prefer the ones that actually look like they could exist in real life. It seems to me that DC comics is particularly guilty of this, which is a shame, because I like DC story lines better than Marvel. Actually, these days I'm mostly reading Dark Horse comics because they are pretty good at making believable characters rather than slutty-looking heroines and bodybuilder heroes. I'm actually enjoying reading Knights of the Old Republic right now that chronicles the misadventures of a scrawny failed Padawan, Zayne Carrick. He and his friends actually look like normal people (except for those that are actually aliens) and have believable characters. I must say that, despite it's many various artistic inconsistancies (not sure about the spelling on that because the only person I have to ask is my chemistry teacher who really can't spell) it is indeed my favorite comic story to date. Among the others I enjoy and am following are Crimson Empire, Clone Wars (the classic ones, not the new ones with the wooden-looking people), Legacy, Dark Times, Rebellion, Trinity, Teen Titans, and Justice League. Good stuff. No school tomorrow! Yay veterans!
