Personally, I much prefer unique styles. There are a lot of comics that, while they may have "good" art, all look identical in style and could have been created by the same person/studio. I find that incredibly boring and my brain just sort of checks out and I will lose interest very quickly... unless the story is good.
I will always pick a good story with bad art over a bad story with good art. I've tried to read some translated comics, but if the dialogue is really disjointed because of a poor translation, I find that I really have trouble following and understanding what's happening. That's an immediate reason for me to stop.
I've subscribed to some comics where I adored the style, but the story was really empty or seemed to have no direction and made no sense. No matter how much I want to like the author and their work, I eventually move on, because it's just painful to read. I've seen several that were super popular and I can't understand how they are successful when there's little to no story, or it takes months to years of updates for even a glimmer of outline for a plot point. Perhaps I am in the minority because these are often the ones that get picked up as exclusive and featured content.
That all being said, there is definitely a point where "bad" art--be it inconsistent drawings, or typography and layout choices that distract from the work--can ruin a good story. Growing and improving your skill is always a good thing--unless you are just content to hide under a rock and make all your work without any outside comments. But you definitely should seek out constructive critiques that will help you grow and tell your story better, which is not at all the same as some requirement that everyone should be criticizing art in comics.
General critiques are probably better than specific ones. You don't need to know on this one page that your proportions were really off, maybe you were trying something challenging that didn't work out. But something like: your font is difficult to read, your backgrounds distracting from your characters, or some other quality that is persistent throughout your work that may be distracting from the message you want to get across, are probably the things that will help you grow as a storyteller.
I think basically, similar to what others said, this is not illustration, this is visual storytelling. Critiquing elements that help you be a better storyteller is what's important, commenting on the art is not always beneficial.
