Likely to delight animation aficionados more than children or their parents, The Powerpuff Girls Movie -- in which the title superheroines make an ultra-frenetic leap to the big screen from their popular Cartoon Network series -- is a shade too dark for youngsters and a touch too juvenile for older Puffsters. That said, the girl-power message is as strong and entertaining as ever (though power here translates to the ability to flatten a city). But the story -- focusing on the bug-eyed girls' bumpy beginnings -- unfolds with the sort of hyperkinetic geometry only a ''Tron'' fan can fully appreciate.
