The teens from “The Maze Runner” are still running, but while they cover more ground in this second film in the series, they never really go anywhere. The sequel is bigger in scope, but that doesn’t necessarily mean it’s better. Plus, by this point, all these dystopian-future, sci-fi dramas based on Young Adult novels are essentially interchangeable. Which one has Kate Winslet as the icy government villain, and which has Patricia Clarkson? I try to sort it all out in my RogerEbert.com review.
