However, as the story of an intercontinental odyssey, it ends up far too condensed to be emotionally affecting. In case you missed the original, the second entry (called Greenland Migration on screen, a title with accidental SEO prescience) gets you up to speed with some quick flashbacks, and one hilarious retcon. Greenland 2: Migration follows up the surprising success of the first. That Greenland 2: Migration works at all is a testament to Waugh’s skill as a craftsman of enormous action, and of post-apocalyptic mood. Greenland 2: Migration is playing in theaters now.
