Guardians of the Crescent Moon Kingdomis the closest in spirit to the popular TV series of threeNarutofeatures. Under the guidance of Kakashi-sensei, Naruto, Sakura and Rock Lee are assigned to guard Michiru, the fabulous wealthy Prince of the Moon Kingdom, and his spoiled son Hikaru. Michiru is so rich, he buys an entire circus so Hikaru can have the saber-toothed tiger that catches his fancy. A storm at sea and a revolt in the Kingdom provide Naruto with the opportunity to teach Hikaru valuable lessons about friendship.   Although Naruto manages to slurp down some ramen, he doesn't crack raunchy jokes or pull pranks. This kinder, gentler knucklehead makes a surprisingly touching teacher.Guardians of the Crescent Moon Kingdomis more satisfying and more entertaining thanNinja Clash in the Land of SnoworLegend of the Stone of Gelel.   Director Toshiyuki Tsuru uses rapid intercutting effectively to pump up the energy in the climactic battle that puts Sakura, Naruto, Rock Lee, and Hikaru to the test. The most interesting extras on the second disc are the footage of the voices of the main characters dubbing the film together (anime voice actors normally record their lines alone) and a Ninja Quiz that cleverly re-purposes footage from the movie.
