exit is a great film, i think it paints banksy as an ass, the five minutes of 'life, remote control' was mind blowing, even despite the derision with which it is presented, and to think banksy watched that and thought, 'i have make my own movie because this is trash and i can make a good movie' seems like a narcissistic dick move,
plus the anonymity made sense when it was illegal... but now it plays like a gimmick when people tear down walls of buildings to sell of work attributed to banksy, or the banksy collective,
i agree, though for me, without his west bank work i would completely write the guy off
this bbc doc is a nice companion piece:

it is called, Graffiti Wars, and is about Robbo the UKs original tag celebrity, also has a segment about blek le rat who, depending on your loyalties, banksy is an inferior derivative of or who is banksy's muse or mentor or inspiration
