“Greenland 2: Migration” (**1/2 out of four) was a mildly engrossing sequel to the 2020 action melodrama about the Garritty family (Gerard Butler, Morrina Baccarin, Roman Griffith Page) forced to leave the solitude of the Greenland bunker and embark on a perilous journey across the frozen wasteland of Europe to find a new home. Visually spectacular with lush cinematography from Martin Ahlgren but dramatically it misses the mark and has too many lulls. Butler’s impassioned performance makes this hit-and-miss film overall worth watching.
