Just watch the preview. Literally nothing happens besides some false friendships due to shared trauma, delirium due to lack of sleep, and the men getting shot when they stop walking. No significant back story, real explanation of what’s going on, and the ending leaves you with nothing. Think how they ended the Sopranos type ish. 90% of the movie consist of the men telling stories, telling jokes, and pushing each other to continue walking which was counterproductive since only 1 person can win. The best thing about the film to me was the popcorn i ate. However, i only got a medium so my joy didn’t last long. Hope this helps, save your money folks.
