I happen to agree with your first para, but I think indifference and dislike are separate
I am indifferent to warhols work because I already agree with the inherent message and find little beyond that message
You can even dislike Warhol for other reasons, but it still remains that disliking the work for its mass production qualities means you are responding as intended
As for your second para.. you seem to be an adherent of a dull and unskillful ideology
I think all art takes skill, of varying types of skill, but more specifically a lot of modern art(o) consists of paintings that inarguably required a lot of skill to paint
You seem to be arguing something other than modern art
Personally I think it's dangerous to apply limitations on how others can express thaemself
It's a cheap win. I dislike being punched in the face. I have no intention of going to an art gallery where they punch people in the face and then say "told you so".
I like skill and flare. Warhol had neither. I don't expect a painting to be like a photo. I just find Warhol devoid of any interest whatsoever. And his apartment had none of his genre in either, probably because he knew he was simply playing the media. Just like Damien Hirst or Tracy Emin and their entourage of sycophants.
I love many of the pics on that link. I wouldn't put Warhol anywhere near any of those artists.
This for me is the part I hate about modern art. Stop being self-referential and paint something that takes skill.
