Interesting thread. Lots of concepts and ideas that I am not familiar with. The level of emotion, both pro and con, shown here is fascinating. I suppose I could refer to myself as "art-blind". Paintings, sculpture, etc that I have seen in books, tv, the web, etc. just do not "excite" me or inspire me to want to see the real thing. Sometimes I think I can appreciate the talent involved in their creation, and some items look nice enough that I wouldn't mind having them in my home (I quite like the expensive Picasso shown up-thread), but I have no interest in going out of my way to see any of them.
I have been to an art exhibit once - M C Escher about 40 years ago at a local university with a girl I wanted to impress. I came away thinking that the Escher book one of my friends owned was a much more convenient way to look at them (and the relationship never really went anywhere). I have also seen paintings displayed during tours of historical sites in Britain - Hampton Court etc. I paid very little attention to these. There were much more interesting things to see in these buildings.
So, nothing really to contribute to this thread as I have no opinion on Jackson Pollock's work. Just thought I would give an art perspective that has not been mentioned yet - one of almost complete indifference
