I wonder. I imagine that a writer would be pleased to see a book he/she wrote praised in reviews. However, if the review is negative, would he/she be upset? I guess some might be. Others will just dismiss the negative comments as those of an incompetent individual who is incapable of writing a book, and thus makes a living as a critic of what others write. Maybe the same is applicable to critics' comments about musicians' works?
I, for one, would first look carefully at what the critic has written in a review of one of my works. I would then read what the critic has written in the past. All this information would help me decide whether to respect the critic's opinion or dismiss it. Of course, a competent critic can have a bad day and an incompetent one can have a good day.
I guess the bottom line is what is the basis of the critic's negative or positive comments? A comment such as the one in Abel's review of Bix's "In A Mist," namely, "It was just so-so" is meaningless because it is not based on a detailed musical analysis of the work. Just the expression of an opinion without providing a basis for it, an analysis of the factors that lead him/her to arrive at that opinion is not very helpful.
