Thick Skinned or Standing Firm?

With the approaching launch of my novel, I have read numerous blogs and articles about book reviews. Even  the most intriguing and well-written stories receive some bad reviews, and my work will be no exception. I think I'm mentally and emotionally ready. I think.

Stories, like art, are subjective, liked or disliked based on the viewer/reader's preferences. Does a bad review mean it is a bad story? Not necessarily, and then, maybe.

As with all criticism, the comment must be evaluated. Does it have merit? Would it improve the art to accept the suggestion? Or, is it only a personal opinion that doesn't bear any true relation to the quality of the art?
