This film could have been a lot worse. Resembling nothing so much as a souped-up episode of Power Rangers, this condensed and Hollywoodised version of a popular Japanese manga mixes watery cross-cultural message-sending with the usual randomly assembled "mythology" that seems designed primarily to sell trading cards.
A chipmunk-faced teen must collect a full set of glowing red globes (with much innuendo along the way) to prevent some latex-encrusted goon destroying the planet. The cast take it all incredibly seriously, which helps; and the story motors along at a pace that - just about - forestalls the creeping boredom that normally afflicts anyone over 12 when they sit down in front of this sort of thing. But, in patches, this is almost funny and nearly exciting. Much better than a flying kick to the head.
