Art (considered exceptional or not) is a very, very subjective subject as is it's value to those who like or dislike it.
I look at things by Hieronymus Bosch, Dhali, Constable, Roger Dean, Jack Vettriano, Lowry, Peter Howson etc etc even Eric Auld (who was head of Art at my Secondary School) and I'm drawn in to the story being depicted within, a lot of which is down to interpretation by the viewer in many cases.
When I see sculptures or twisted metal or shapeless lumps of clay, dead cows, piles of bricks (not referring to the Spanish building here by the way) and such crap passed off as art and valued sometimes at hundreds of thousands of pounds I am left rather cold and uninterested. Others will differ on their opinions and think such things are wonderful and valuable.
Architecture as an art form (and no doubt at times it is) leaves me in pretty much the same boat and that'll not change tho I do have a soft spot for some Art Deco buildings.
The fact something draws money to and area or city to me is not sufficient for being a particular fan of that thing. Up where I live the Royal Family bring millions to the area every year in tourism etc which is fantastic for local businesses and the economy of the region but that doesn't mean I and everybody up here has to be a Royalist, and I'm not (not particularly anti neither) and I have met and spoken to the Queen. Just my feelings like.
