If you click on the above title line, you will be whisked off to an article that appeared in the London Daily Mail.
It seems some English journalists wanted to find out what you and I, the art viewing and museum going public want to spend our time looking at in a museum. In order to write this article they spent time sitting in galleries in The Tate Britain, a world-class London museum, and they clocked how much time visitors spent on a variety of different works, in a very broad spectrum of genres. I won't blather on because you'd be much better off just reading the article. Seems we don't show much interest in the 'body parts and dead animal' school of modern art....or the 'field of dots that look like wrapping paper' school.....or the "....here I am sitting in a chair in the desert" genre of photography....or pretty much any of that crap, in fact.
It should come as no great revelation that we want to look at art that moves us emotionally, touches our humanity, enriches our sense of beauty, has a little poignancy, maybe a sense of the poetic....and is just plain accessible without a masters in the history of art.
