I'm not sure if this would be interesting to see or not. It could very well end up being an exercise in watching sheer bloody mindedness. The vigilante chap who's wandering around painitng over graffiti seems so confident and sure of himself, that he's in the right, and ... pleased that the graffiti artsits will never stop him. It's not clear from the trailer whether he thinks that he can stop the graffiti artists. If he does, he's in for a lifetime of dissapointment.
And seriously, how repugnant is the guy who says that graffiti conveys the impression that decent people do not control the streets? Very is the answer. Guess who gets to determine who is a decent person or not in his world? Betcha it's him and that decent people are people like him who only behave exactly how he wants people to behave. I'm not entirely sure I could stomach watching more than that few seconds worth of interview with him.
I believe Streetarse is right, in that the Auckland City Council should watch this sort of thing, try to understand street art rather than dismiss it and insist that we should only be looking a official committee approved art or advertising. Kingsland for one would be a much poorer place without our street art.
