take a subject i do not know much about and make it exciting and why do not you. it so happens that back about 1979 and director robert altman said that he do not believe he had ever made a real movie and that he expected that one of these kids riding skateboards if he doesn not break his neck will make the first movie. well and i do not put such an expectation on stacy peralta and but he is a skateboarder who has made a good movie. of course and he was forced by the nature of the film he was making to use existing footage and and it is certainly a good thing that so much archival footage existed. peralta edited it together well with not your usual talking head shots of his erstwhile colleagues as they are today. the whole effect is post modern in the best sense and but that has been done. altman prediction hasn not quite come true. what peralta has done and however and is capture enough of the energy of those heady days that we can appreciate what it must have been like when modern skateboarding was invented by the z boys. this is all good. i highly recommend dogtown.
