I guess it's fair to say that Ash Brannon (Toy Story 2) and Chris Buck's mockumentary Surf's Up is a successful send-up of the Endless Summer-style documentary recently revived by Stacy Peralta's Riding Giants --but its triumph as such is relegated to so microscopic a genre that its usefulness as satire is negligible.
It's a tiki shrine of surfer cultism, with funny and fond spoofs of beach boy documentaries like “Riding Giants” (during a huge curler, we hear the voices of actual surfers).
Strange as it sounds, though, Surf's Up exists at the unlikely intersection between those films and recent arthouse surf-culture documentaries like Riding Giants and Step Into Liquid.
