Short review of three little words: Way. Too. Long. Nearly two-and-a-half hours — what? — to remake a 1984 movie about a kid who learns karate from a master so he can beat up bullies. (Peter Travers reviews The Karate Kid in his weekly video series, "At the Movies With Peter Travers.") The original had New Jersey teen Ralph Macchio learning karate from the great Pat Morita in California. The reboot has Detroit kid Jaden Smith, the 12-year-old son of Will and Jada, learning kung fu from the great Jackie Chan in China (cue the travelogue footage). For a movie whose outcome is never in doubt, the padding is punishing.

Peter Travers picks the season's can't-miss films and the ones with a bad vibe in his summer movie preview.

“I'm Yours”

Jason Mraz re-emerged after his disappointing second album with this lead single, a Jack Johnson-esque ditty about giving yourself fully to someone else. The success of the reggae-tinged song (it earned two Grammy nods and a spot on the Billboard singles chart for well over a year) was something the folk-pop singer never predicted when he wrote it in 15 minutes at home. "I played a happy-hippie chord progression that would probably work without 50 different Bob Marley songs," he told Rolling Stone. "I thought, 'It's too novelty. This is a nursery rhyme,'" concluding that "you can never guess what's gonna be a hit."
