What makes "Great Art"?

I chose to watch Warm Bodies(2013) along with West Side Story(1961).  I found this version(Warm Bodies) of Romeo and Juliet to be entertaining.  The story was modified to fit pop culture and the intense interest in zombies and the apocalypse.  As I was reading Bourdieu's piece, he included a quote by Suzanne Langer that said, "But now that everyone can read, go to museums, listen to great music, at least on the radio, the judgement of the masses about these things has become a reality and through this it has become clear that great art is not a direct sensuous pleasure.  Otherwise, like cookies or cocktails, it would flatter uneducated taste as much as cultured taste." As I read this quote, I understood it to mean that great art is not something that can just be consumed, you have to be educated to understand the deeper meanings behind it.  Is Romeo and Juliet still a product of high culture?  Especially in the Warm Bodies adaption of the story, I feel like the story has been adapted to fit popular culture and has created new ideas that did not exist in the original story.  Besides R, the zombie, Romeo and Julie being the human, Juliet they were not really star cross lovers and there was less of a focus on the other characters except for the role of Nora as the best friend/advisor.  The major theme seemed to be that love and understanding can change even the toughest of hearts.  That seems to be quite different from the original Romeo and Juliet.
