Read a spoiler-free review of "Captain America: Civil War." Rating: 3 of 4 stars. The third movie in the franchise, entertains relentlessly, which is to say loudly and busily, but with enough humor and intelligence to make it seem less pandering than it actually is. It's here to provide explosions, stunts, big-budget effects and the answer to such burning questions as: Who would win in a fight -- Captain America (Chris Evans) or Iron Man (Robert Downey Jr.)?
