LOS ANGELES, May 28 (UPI) -- Power Ballad , in select theaters Friday, introduces several provocative themes about creativity and the music industry. Unfortunately, it only pays them lip service and leaves many important ones on the table. Rick Power (Paul Rudd) is the lead singer of an Irish wedding band who loses the party crowd when he plays his own originals from his U.S. touring days. At one wedding, the bride invites her childhood friend, former boy band singer Danny Wilson (Nick Jonas).
