Exit Through the Gift Shop

I think street art is illegal. If the artist is putting his or her art on something to them, which is how most of them do it, then it's illegal. If whatever they are putting their art on belongs to them, then obviously it is legal. To me the difference between art and graffiti is art is legal and graffiti is not.
I don't think that Mr. Brainwash is a real street artist. He only got into it because he was around it and filming it. He's not a real artist either because all he did was take other people's art and change one or two things on it and called it his own. He didn't have any original work.
Banksy did take over the film, but he didn't take over it because of selfish reasons. Guetta had no idea what he was doing and that was evident in the film that he made on his own. So, yes, I think Banksy had a right to take control of the film. I think the "real" reason he takes over the film is because he's a real artist. Maybe he wanted to expand from street art and start directing. A new form of art and expression for him.
I think Banksy tried to be a good friend to Guetta, but Guetta used him and ruined the friendship himself. They started off being friends and Banksy offered to help him start his own career. In return though Guetta used him to become popular and get his name out there. Banksy could have made Guetta look a lot worse that what he did in the film, but he didn't.
I think the Disneyland stunt was to get people thinking and so he could see the people's reactions. This probably wasn't the best way to go about it though.
Guetta is successful in his art show because he makes a lot of money. A lot of people come to see his show and a lot of people buy his art. He fails because in order to get this "success" he uses his friends and family and thinks only of himself. He fails because he burns bridges and loses friends.
I think his fans at the show have no idea who Mr. Brainwash really is and the only reason they are there is because it was so well advertised. If they saw this documentary their opinions on him would probably change. They don't know the background of the art they saw and bought. Guetta himself put little thought into his art. It was the people he hired who did the work.
This film started off as Guetta's, but as it goes on, it is clearly Banksy's. The reason it is called "Exit Through the Gift Shop" is because Guetta's art show was all just a ploy to get money. His art didn't have any meaning to him, he just wanted to be able to sell it for as much as he could.
I don't think this film is a hoax. I think it is a real story on how Mr. Brainwash came to be and it was basically over night. He didn't have any history, all he did was decide he wanted to be an artist and the next day he was naming himself Mr. Brainwash.
The statement this makes about the art world is they either don't care about real art anymore, or people who know nothing about art are taking over. The media attracts to anything that causes a scene. But the real street artists know what real street art is and have no respect for Mr. Brainwash with reason.
