One of the biggest criticisms levelled at comics - aside from their repetitive, recycled nature - is the fact that they are dominated by one genre or type: superheroes.
I could get cute and claim that Hawkman and Hawkgirl encompass science fiction,romance, supernatural, detective and fantasy right there. They proved that the earliest superheroes - created in wartime - were not exclusively preoccupied with the ideological battle between Allies and Axis (though spy and war comics flourished, as did superheroes in the Theatre of War).
In ensuing posts I will explore the histories of non-superhero comics.
