“It is the business of a comic poet to paint the vices and follies of human kind.”

Context: Take care that thou be not made a fool by flatterers, for even the wisest men are abused by these. Know, therefore, that flatterers are the worst kind of traitors; for they will strengthen thy imperfections, encourage thee in all evils, correct thee in nothing; but so shadow and paint all thy vices and follies, as thou shalt never, by their will, discern evil from good, or vice from virtue. And, because all men are apt to flatter themselves, to entertain the additions of other men's praises is most perilous. Do not therefore praise thyself, except thou wilt be counted a vain-glorious fool; neither take delight in the praises of other men, except thou deserve it, and receive it from such as are worthy and honest, and will withal warn thee of thy faults; for flatterers have never any virtue — they are ever base, creeping, cowardly persons. A flatterer is said to be a beast that biteth smiling: it is said by Isaiah in this manner — "My people, they that praise thee, seduce thee, and disorder the paths of thy feet;" and David desired God to cut out the tongue of a flatterer.
But it is hard to know them from friends, they are so obsequious and full of protestations; for as a wolf resembles a dog, so doth a flatterer a friend. A flatterer is compared to an ape, who, because she cannot defend the house like a dog, labour as an ox, or bear burdens as a horse, doth therefore yet play tricks and provoke laughter. Thou mayest be sure, that he that will in private tell thee thy faults is thy friend; for he adventures thy mislike, and doth hazard thy hatred; for there are few men that can endure it, every man for the most part delighting in self-praise, which is one of the most universal follies which bewitcheth mankind.

Context: If I write a crappy comic book, it doesn't cost the budget of an emergent Third World nation. When you've got these kinds of sums involved in creating another two hours of entertainment for Western teenagers, I feel it crosses the line from being merely distasteful to being wrong. To paint comic books as childish and illiterate is lazy. A lot of comic books are very literate — unlike most films.
