Fantastic. Pretty much the reason I watch documentaries more than anything else at this point. For one thing, a documentary is almost never two hours long. Unless it's about or starring Patrick Swayze, I no longer have two hours of my life to devote to a movie. Plus, nothing explodes. Not a single thing. Remember that guy in the early seventies who walked on a wire strung between the Twin Towers? Well, this is about him. 'Nuff said. Rent it. Now.
