Da Vinci Code' misses the mark for critics

The Cannes audience clearly grew restless as the movie dragged on to two and a half hours and spun a long sequence of anticlimactic revelations.

"I kept thinking of the Energizer Bunny, because it kept going and going and going, and not in a good way," said James Rocchi, a film critic for CBS 5 television in San Francisco and the online outlet Cinematical. "Ron Howard makes handsome films. He doesn't make bad ones, but he doesn't make great ones."

One especially melodramatic line uttered by Hanks drew prolonged laughter and some catcalls, and the audience continued to titter for much of the film's remainder.
