But The Big Reveal of what happened to these kids, who trapped them in this place and what their purpose is ends up being pretty over-the-top even for sci-fi. A lot happens in the film’s final minutes to the extent that it makes “The Maze Runner” feel like it has several conclusions. Some of them feature some unintentional hilarity when shock and fear probably were in the game plan. And they squander the formidable and versatile Patricia Clarkson in only a few moments as the chilly, nefarious mastermind of the maze.
