This is a super interesting documentary the BBC did a few months ago. It focuses on one of the issues the art-world has been debating since the birth of Modern Art: can art really be considered "art" simply because of its concept? or is art "art" because of its beauty?
The title of the program may give away the program's opinion...even so, it's definitely worth watching. I won't tell you my opinion just yet, you have to watch it first: http://www.youtube.com/watch?v=65YpzZrwKI4&feature=PlayList&p=71A4A928111A6006&index=0&playnext=1
