"Okay Thanks, but Kinkaide is not art."
Art is in the eye of the beholder. Evaluation of what passes as art is subjective, not objective. Kindaide is successful for a reason.
Truthfully, art is not so subjective, except for "modern art," which is not what Kincaid does. Realism is very much a craft which has actual standards.
IMO Kincaid has ability as a craftsman, but my feeling is that his stuff is not straightforward or honest. This seems to be born out by various news stories and anecdotes about him.
The word subjective does apply to taste, on the part of both the craftsman and the viewer.
Of course it is art!!!! Don't be silly!!!! The person who designs a logo for a can of green beans is doing art!!!! A person who creates a kitty cat for a greeting card is doing art. A person who designs the pattern for Hallmark wrapping paper is doing art. The person who designs a flower pattern to be embroidered on bath towels for Canon is doing art! Kinkciade is a decorative artist. If you like his work fine, if not that is okay too. But at least understand that "art" covers a very wide gamut of creative endeavors from important to trivial.
And it's the same reason that people collect Precious Moments or Beanie Babies.
A. No taste, so they really like them.
B. Deluding themselves that the things will go up in value.
