Yes, agree.
Lots of people here are saying that art is not so important, but I'm going to bring up a counterargument:
The examples people are showing here are not actually bad. They still have a good grasp of comic flow, so the stories are able to shine through. I would call One Punch Man and XKCD functional art, not bad art.
Comics with truly bad art are never read at all, because their art is so incomprehensible that we can't even tell what the story is. I've seen this even with very good artists that can draw a body perfectly but can't board a comic for shit. Without at least a minimum level of artistic skills, there can't even be a story. It would be like trying to write a book without knowing the alphabet.
Also, since a lot of people are giving recommendations for their favorite "bad art" comics, I wanted to add one of my own:
Doe of Deadwood
As you guys can see, the art is pretty plain. I even thought it was kind of ugly, and that the fact that the main characters are animals was weird. But the writing was good enough to pull me in, and now it's one of the few comics I follow for every update.
But despite the art not being the best, the artist knows his limits. He never crams too many details into one panel, and his characters' actions and expressions are very clear. He uses enough panels to convey actions clearly but not so many that it gets boring. I've never felt confused as to what is happening in the story.
It's the same for the examples everyone else is bringing up: a good story needs at least a minimum level of comic making abilities to be decent.
