When I was reading comics, shitty art could stop me from enjoying a comic book.
A good example was the short lived Hex series.

I actually really enjoyed that book, but could not get into the final issue(s) because of the art.
Normally, I like Giffens art, but on that book it was fucking awful.

For all I know, the wind up on that series was great, but I totally zoned out on the story as the art was so distracting (in a bad way).

Its kinda like films.
The story and script can be ground breaking, but if the camera work and acting is terrible, the good things cannot be enjoyed!
