No. But doesn't to be really good either. Comic is more about sequential visual art rather than just art + text. So if you can tell a story you want to tell panel by panel through your art I think that's good enough. Depends on the reader though, it can be the best story written carried by the best artist in the business if the reader is not into the genre they probably wouldn't touch it.
I mean just look at the most popular comic, manga, Webtoon, etc pretty much all are mediocre at best. Some are garbage coated by fan service but I don't mind killing time reading them.
Then look at Pax Americana #1 by Grant Morrison and Frank Quietly. One of the few comics that should be a required academic reading for all comic creators. Here are all the theories in Understanding Comic and Making Comic delivered perfectly in a way Scott McCloud could ever hope to see in his lifetime, in one compact issue. How to guide the reader, give them subtle or not so subtle hint, misdirect or confuse them altogether. Add another layer of dissing your long-time rival in every way you could possibly imagine through:
1. Paneling number
2. Core theme
3. Characters
4. Every time and every way that permits you to do so
All of these meta playing on the pages of these beautiful artwork is freaking godly in each of the pieces, but as a whole I find it very hard to like. I almost freaking hate it. And that meta is played, predicted perfectly on the scene where Dr. Atom dissects his pet dog, part by part in mid air telling the exact same thing.
That. Complete. The. Infinite. loop
Inside and outside of the comic. A masterpiece that is so perfectly beautiful yet the reader may utterly hates it.
TLDR: maybe
