When's the last time a movie really sent your heart soaring? Richard Curtis' ("Love Actually") "About Time" may be sentimental and not always believable, but A. It's a movie about a guy (Domhnall Gleeson) traveling in time to perfect his pursuit of his love (Rachel McAdams); of course it won't be logical. And B. Those elements are forgivable when affectionate performances create characters we fall for as they're falling for and/or supporting each other. "About Time" is warm, romantic and aware that sometimes the nicest moments are the smallest.
