I strongly disagree. Plenty of comics have some very high quality and detailed art. Other comics really evolve over time, from the more basic sketches to these fully realized complex images, as the artists themselves improve. Still others are sloppy-but-ambitious, with these poorly conceived but legitimately daring efforts at capturing visuals.
I know XKCD does more than 1 thing but the art style is literally stick figures and they’re one of the most popular web comics.
Perspective, emotion, action, comedy, a very well-established cast of characters from simplistic visuals. All from stick-figures. There was some real thought put into this.
