In `Legally Blonde,' which could well be re-titled `Clueless Goes to Harvard' - the delightful Reese Witherspoon stars as a ditzy, fashion-obsessed airhead who winds up (through plot complications too elaborate to go through) taking that Ivy League law school by storm. Needless to say, there is not a single believable moment in the film, but that is generally the case with most fish-out-of-water scenarios anyway. What `Legally Blonde' does have is a warm spirit, a bubbly demeanor and a breezy charm that reflect to a tee the personality of its main character.
