This is an odd, disorienting commodity -- a fictional version of a documentary (Dogtown and Z-Boys) about the birth of skateboarding in 1970s Venice, California, that was written by the man who directed the doc, in which he was a central figure. Stacy Peralta is fast becoming one of those guys you find in a neighborhood tavern who keeps regaling patrons with stories of ancient glories. He just can't stop talking about those good ol' days when he and his fellow Z-Boys were sun-tanned gods riding their wooden decks into the golden sunrise courtesy of the skateboard magazines of the 1970s that ran action-packed pics of SoCal kiddos laying tracks in drained swimming pools. One could almost understand the existence of Lords of Dogtown had the documentary been somehow deficient in its telling of the tale, but it left out nothing. These guys were self-mythologizing long before anyone outside their circle knew their names. But with Peralta there is no end of story, only more of the same.
