WHAT WOMEN WANT (2000) is a passably watchable romantic comedy, but it does have a couple of moments of joy. Mel Gibson dons a fedora and dances to Sinatra’s “I Won’t Dance.” Even better, Helen Hunt pops a cork to the strains of “I’ve Got You under My Skin.” She sings along with Frank, dances too, and the song lives right through her, a bravura performance.
