Ditto. I always thought of Kinkade as a talented illustrator. Norman Rockwell is a good comparison. The fact that he was reviled by the art establishment is a point in his favor. Kinkade's stuff is not my cup of tea -- a little too sentimental -- but it is at least pretty, which is better than a lot of what populates museums and exhibitions these days.
People collect poster art, some of which commands a pretty hefty premium. Nothing wrong with that. I suspect a lot of the hostility to Kinkade stems from the fact that he was so openly commercial, and made money.
