All art critics find it difficult to discover art works that truly satisfy them. A work of art that receives extensive critical attention can thereby become more widely known than it otherwise would have been. The greatest works of art are works that inevitably satisfy all critics. No art critic enjoys writing about art works that he or she dislikes intensely.
Many artists claim that art critics find it is easier to write about art that they dislike than to write about art that they like. Whether or not this hypothesis is correct, most art criticism is devoted to art works that fail to satisfy the critic. Hence it follows that most art criticism is devoted to works other than the greatest works of art.
