Some of the greatest songwriting teams of the 60s were romantic couples (Gerry Goffin and Carole King, Jeff Barry and Ellie Greenwich, Barry Mann and Cynthia Weil), but this Valentine's Day release doesn't do much with the idea of lovers crafting hits together. Most of the laughs come from Hugh Grant as a genial 80s has-been (modeled on Andrew Ridgeley, the forgotten half of Wham!) who's made peace with his current gig playing amusement parks and high school reunions as a retro boy toy. Drew Barrymore is that rare movie starlet who can handle the comedy end of romantic comedy, but she coasts through her underwritten role as a goofy plant sitter recruited by Grant to write his lyrics. Marc Lawrence (Two Weeks Notice) directed; with Campbell Scott. PG-13, 96 min.
