But you've proven my point. Dark Knight is not your traditional batman film, as it's marketed as a crime thriller and was toted as a movie that is a "realistic" comic book. Batman has not been nerd forsome time. Cloverfield, not nerd, Watchmen a classic graphic novel (again marketed to seperate itself as a standout) and as star trek has gotten the makeover I told you about to denerdify it. Hot characters, popular director (who makes hip scifi), and a revamp of updated tech.
That's also not to say that putting a lot of money behind something and throwing out of the nerd realm and into pop culture doesn't help. (LOTR)
REst assured, nerd is still not bankable. Take scifi shows on regular and cable tv. A show, like alost or heroes, has to make steps to denerd it, and put it in normal worlds so that its not so nerdy. The minute it takes a nerdy turn, the ratings start to tumble
