This determinately unoriginal rom-com tries to fit in every cliché in the book and nearly succeeds. Amy Adams is an American woman who can't get her boyfriend to propose. She hears some convenient legend about how women can ask men to marry them every Feb. 29 in Ireland, so she comes up with an elaborate plan to pop the question there. But the unreliability of mass transit in romantic comedies conspires to send her on a cross-country odyssey with a hunky Welsh taxi driver (Matthew Goode). You'll never guess how it all ends. Oh, wait. Yes, you will.97 minutes PG.
