Banksy.. some say he's an 'art terrorist' thoughts?

I was suprised SO many people don't know who Banksy is.. I thought he was pretty mainstream in art culture. However I just saw his documentary this past weekend called Exit Through the Giftshop, which I really enjoyed. Has anyone else seen it?

If you have answer this question... do you think that MBW was created by Banksy, Fairey, and all of those who agreed for him to film them? Someone asked me the same question. I am probably botching it, but do you feel like Banksy encouraged him to create art instead of film as a joke on those who would buy it? I guess I don't want to give it away if people haven't seen it, but e-mail me because I would love to converse with you! (monica.vonrueden@gmail.com)

Anywho... besides the documentary I am really fascinated about his art and the way that I feel he sets himself apart from other graffiti artists. How can you set your work apart from others that are doing similar projects? I have thought about that ever since I walked out of the movie theatre.
