The stereotypes applied to comic book nerds hold pretty true. Almost all of the comic shops I've been to in this great nation of ours are staffed with the same type of people - you have your "rocker" - the guy in a leather jacket with long hair who seems to be left over from 80's metal band avalanche -he only reads zombie comics, occasionally expanding his tastes to something commercial like Spawn. There's the rail nerd, done up in Superman shirt and knows everything there is to know about comics - from the 90's onward. To him X-Men only got good when Rob Lefield took over - course he would never admit that in a room full of people. The fat goatee - who looks down on those who enter the store. The geek is sheik wave has granted this 4 tacos for a dollar fan with knowledge that allows him to keep conversation with normal people when the latest Iron Man movie hits the screens, sadly he confuses his comic book intellect with personality and doesn't understand why these people don't hang out with him outside of the store. You have the "female", who on the streets would score no higher than a 6 but in the comic store she's a 10 +. Got into comics because of her boyfriend, x-boyfriend, whatever. Cosplay is more important than comics. There was a time where these women could easily be spotted by the Elfquest books under their arm. Then there's the Old Man -- doesn't really like anything that came after the 70's and could teach you a thing or two about CC Beck, Kirby, Ditko -- if his memory was as good as it used to be.
All of the above (with exception of the Old Man) are cinefiles and their two favorite films are Citizen Kane and Boondock Saints. When it comes to movies, most will answer "I'd love to see a version of this done darker and starring Bruce Campbell."
