The latest from Disney Animation is a wild and imaginative exploration of a video-game fantasy, i.e., what happens in the lives of our favorite game characters when we’re not playing them? Ralph (voiced by John C. Reilly) is weary of his prescribed lot in life: He’s not a bad guy, so why does he have to play a bad guy in the arcade game Fix-It Felix Jr.? Ralph goes on the run, teaming up with Vanellope (Sarah Silverman) to traverse the video-game world landscape and grapple with the modern-era game soldiers led by Sgt. Calhoun (Jane Lynch). It’s fun enough, but a bit hectic.
