I recommend Susan Sontag's great 1964 essay "Notes on Camp" to all cartoonists and comics enthusiasts.
"41. The whole point of Camp is to dethrone the serious. Camp is playful, anti-serious. More precisely, Camp involves a new, more complex relation to "the serious." One can be serious about the frivolous, frivolous about the serious.
42. One is drawn to Camp when one realizes that "sincerity" is not enough. Sincerity can be simple philistinism, intellectual narrowness.
43. The traditional means for going beyond straight seriousness - irony, satire - seem feeble today, inadequate to the culturally oversaturated medium in which contemporary sensibility is schooled. Camp introduces a new standard: artifice as an ideal, theatricality.
44. Camp proposes a comic vision of the world. But not a bitter or polemical comedy. If tragedy is an experience of hyperinvolvement, comedy is an experience of underinvolvement, of detachment."
