ABOUT A BOY - As bland and forgettable as its title. Paul and Chris Weitz's mostly lifeless work begins well, but you can feel the sickly sentimentality creeping up on you, and you just know you're going to have to endure a series of Life Lessons and the grueling prospect of watching Hugh Grant - an enjoyably pathetic sloth - better himself as a human being. Like all sitcoms posing as movies, everything rough-edged is ignored to ensure Happy Endings for all.
