Comics are a medium, not a genre. To wit: there are science fiction comics, just like there are science fiction films and prose. There are superhero comic books and there are superhero movies.
The use of “comic book movie” to describe films as diverse as Superman Returns, X3, American Splendor, and Ghost World is silly and insulting to both media. Nobody ever says “novel movie,” and for good reason. They’ll say it’s a romance movie based on a novel, or a literary adaptation.
Thank you. Next week, we’ll be covering that whole “Biff! Bam! Pow!” headline you people insist on using.
