Yep I know - but a worldwide general audience doesn't - and that's who they want to see these films.
I even overheard two members of staff talking after the first Iron Man film was announced. They were saying the film would bomb as Iron Man was a boring character - even comib
c geeks didn't rate him - now he's extremely popular, all because his film was a success. Now I'd argue GL was a more popular character before that, he just needs a good movie to propel him back up there.
A character isn't defined by a single medium, even when it's something as big as a film franchise. A character's place in pop culture comes with the sheer number of incarnations through multiple generations.
Blade is the perfect example of this. He had a successful movie trilogy (even Trinity made money) and a live-action TV series. That puts the character in elite company among comic books characters, but does that make him one of Marvel's biggest and well-known characters? No. While Blade is one of my favorites ( I prefer his trilogy to Iron Man, Thor, and Cap's movies), the grim nature of the character doesn't easily lend him to multiple forms of translation and merchandising the way other comic book characters do.
While I was disappointed that the GL movie didn't turn into a trilogy, I wholly disagree that it somehow did irrevocable damage to the character, or made him "B-level". 2008-2012 was the most visible the character has even been with multiple video releases, a headlining cartoon, a hot comic that turned into it's own mini universe within the DCU, and many products putting the characters name in the forefront of pop culture. The movie just added another layer to the mythos.
Geoff Johns leaving GL--now
that hurt. GL fans can still look forward to JL: Thone of Atlanis and his eventual introduction to Flash (assuming the show is a hit), losing Geoff's magic has hurt GL's sales and visibility. However, all big characters seem to go through periods like that, so we just have to wait.
