No doubt Comic-Con is, indeed, the nerd prom. Costumes are a big deal here. This week I've seen dozens of imperial stormtroopers, Batmans, Robins, Supermen, and Wonder Women. I've eaten lunch next to Starfleet officers, Princess Leias, elves from Middle Earth, pirates of the Caribbean, Predators, Jedi knights, and multiple versions of Indiana Jones (and even his father). I can't tell you how many different Jokers are on the premises this week.
I have been impressed by the diversity of people here. Bucking the stereotype of the overgrown adolescent geek living in his parents' basement, all over the place you can see little kids, teenagers, senior citizens, and everyone in between. Lots of African-Americans, Hispanics, and Asians are prominent here. And no shortage of women, either, contrary to the clichés.
And the range of interests represented at the convention is equally diverse. There's certainly a fair number here with at best a passing interest in comics--theoretically the centerpiece of the event. There are people into video games, television shows, Japanese anime, fantasy, Star Wars, vampires, and about everything else in the world of pop culture you can imagine. The hot ticket panels are those involving blockbuster films and TV shows with cult followings (such as Lost, The Office, and Battlestar Galactica).
