Despite his unique world view and perspectives on technology, William Gibson is, I'm sorry to say, a little underwhelming on camera. It might be more accurate to describe him as just an ordinary guy--albeit one you could have a very stimulating chat with--and like any ordinary guy, watching a movie of him talking from the backseat of a car just isn't captivating for a whole hour and a half.
Lacking visual content, director Mark Neale splices in an endless montage of television static, stock footage, and technological advancements, presumably in an effort to show how Progress has, for better or worse, cluttered our lives. Occasionally, the jerky jump-cuts and trick-shots serve a purpose, but mostly they produce a mind-wracking effect not unlike flipping through 150 channels in under 10 seconds.
Gibson fans will still enjoy this (I did, despite it's dryness the filmmaker's well-intentioned editing spectacles), particularly to see just what the author of "Neuromancer" is like. It's probably no surprise that he comes across more than a little geeky, but he also seems very grounded, conceding the work he's known best for has an adolescent streak to it, and maturity had led him down a different path as a writer.
