Related to above post: intro narration as an excuse for lazy art.
I just hate when I open up a comic, and the art, instead of being well-drawn pictures of things, is a bunch of scribbly scrawlings, vague silhouettes, stock photos and often with crappy photoshop filters over the top, just any excuse to avoid drawing an actual place, object or person clearly.
Load up the comic... bunch of black space... Then some scrawled stick people I guess are meant to look like cave painting or something, but they just look like half-arsed stick people because no effort or research was put in "Long ago, the people of the world lived in harmony..." Picture of some stock fire "But then... there was a war." picture of a stock bloodstain "Many people died." Generic star texture "But now a new legend will begin?" cliched manga stock image of drop creating ripple in water.... and then I return to the forums where the artist is like "Why is nobody reading my comic, I put so much work into it!" ....Did you though? DID YOU? 
Like okay, if you want to make a comic with lazy art, and avoid drawing things that are hard or take time, then go for it, that's fine, but don't do it and then expect people to treat your lazy comic like it's on the same level as ones by people who understand that if you want to entertain an audience, you need to genuinely try to show them something well-presented with art that tells the story, not just words floating in space and occasional vague imagery chosen based on how easy it was to put in, not how well it tells the story.
