This is obviously…okay, seemingly of a very high order. Maybe. If your idea of “a very high order” is a mixture of Runaway Train, the “political exiles on a long ride to the Urals in a cattle car” sequence from Dr. Zhivago (which incidentally contains my beloved “I am the only free man on this train!” scene with Klaus Kinski) and the “realistic” CG panache of Robert Zemeckis‘s Polar Express. I’m also figuring you can’t go wrong with Tilda Swinton in a scenery-chewing mode
