The “Art vs. Craft” debate seems never-ending, because it hinges on an ever-evolving understanding of how we perceive what is considered “art”.
Fans, publishers, art directors, and collectors expected Worldcon art shows to display the best-of-the-best art being created in the field, and top artists looked forward to meeting their expections. NO MORE.
I must confess, when it comes to SF/F the more you see of it, the easier it is to become innured to its novelty. Familiarity with dragons, wizards, and flying saucers can breed not contempt – but worse: indifference and inattention.
