In some ways street artist are a lot like Internet commentators. You put your feelings out in public, not knowing if people will like it or not. Mostly they are out of context to the average passerby and they are soon forgotten.
The first half of the movie is a love letter to the street art world from the scene’s biggest champion, Thierry Guetta. It’s pretty endearing how a man with a camera and not much finds himself in the world of graffiti. The graffito taggers seem to embrace him early on simply for the fact that he embraces them. He has a strong sense of just needing to create something, which I would imagine also helps to form this bond. A fun symbiosis is formed when they realize that they need him as much as he needs them. The first half of the film is fun and you cheer for the kids(not really kids) who disregard social norms and express themsleves without bothering to check if it offends authority.
