Actually, the promotional materials for his work 
make a rant unnecessary.  E.g.,

"An astonishing transformation takes place when 
Thomas Kinkade's ideas and memories are 
transferred from the man's mind to his paintbrush 
and then finally to the canvas itself. The 
results of this astounding process are clearly 
evident every time you look at a Thomas Kinkade 
painting. What was previously just a blank white 
surface turns into a work of art so real that you 
can't believe what you're seeing."

[That's true: most of my cels are so obviously 
figments of my imagination that I have no trouble 
at all believing that I'm looking at them.]

"Each print is a genuine canvas reproduction 
created with the same methods and materials used 
by Kinkade to create many of his original 
paintings. Each of the prints comes complete with 
a Certificate of Authenticity that identifies its 
status as a First Edition, Second Edition, etc. 
The Certificate also serves as a guarantee that 
your reproduction is a "Genuine Kinkade" and 
matches the original painting to the artist's 
specification."

[Prices start at $219 (plus custom framing and 
shipping) and go well into the $1000-2000 range 
for a "genuine reproduction" on canvas that is 
identical to the canvas Kinkade used as 
the base for his original painting!  The 
Certificate (is that at least authentically 
signed by Kinkade?) proves that there actually is 
an "original painting" that the artist specifies 
as the source of the image copied in the thing 
you get.] 

Sigh.  Certainly makes the most I ever spent for 
any one cel look like the little handfuls of 
coins I used to dig out of the bottom of my dad's 
easy chair.
