Desperate migrants are forced to leave Greenland after a malevolent force makes their island uninhabitable. No, it’s not tomorrow’s headline about Donald Trump, but rather the sequel to Ric Roman Waugh’s 2020 post-apocalyptic survival thriller. That film starring Gerard Butler and Morena Baccarin had the misfortune of opening during the pandemic and going straight to VOD. Greenland 2: Migration (now there’s a catchy title) has the benefit of opening in theaters, but it truly feels like an unnecessary follow-up. After all, how many travails can one poor family take?

That family consists of John Garrity (Butler), whose structural engineering skills designated him a governmental candidate for survival in the wake of an interstellar comet dubbed “Clarke” wreaking worldwide destruction; his wife Allison (Baccarin); and their son Nathan (now played by Roman Griffin Davis). At the end of the first film, the clan had endured numerous life-threatening crises as they made their way to the underground bunker in Greenland where survivors will attempt to make a new life.

Five years later, things aren’t going so well. Fragments of the comet continue to rain down on the planet, causing catastrophic destruction. The contaminated air prevents people from going outside, and resources are becoming increasingly scarce. But there are some plus sides, such as the bunker’s inhabitants still being able to dance to yacht rock.

When their safe haven in Greenland is destroyed, the Garritys, along with a few other survivors, are forced to flee. Their destination is France, where there are rumors of an oasis at the comet’s original crash site. And at the very least, the food is bound to be better.

It’s a perilous journey, but anyone who saw the first film knows what to expect. The Garritys, along with the bunker’s Dr. Casey (Amber Rose Revah), run into some very bad people, undergoing a series of life-threatening trials and tribulations.

Unfortunately, while the thriller mechanics are reasonably well orchestrated by director Waugh (Angel Has Fallen, Kandahar) in his fourth collaboration with Butler, Greenland 2: Migration feels as redundant as its title. While the first film featured a relatively original premise and some genuine emotional dynamics in its suspenseful situations, this one just feels rote. And while it’s made clear that the crisis has resulted in people resorting to cutthroat, deadly means to ensure their survival, the Garritys have it relatively easy. All John has to do is adopt a puppy-dog look, put a pleading tone in his voice, beg for his family’s help, and people inevitably comply.

To be fair, the film contains some genuinely arresting scenes, including one set in a practically submerged Liverpool and another in a dried-up English Channel. The latter provides the opportunity for a harrowing sequence in which the family is forced to cross a giant ravine on a treacherously fragile rope ladder.

Butler remains a sturdy screen presence, his Everyman quality lending gravitas to his character. Baccarin, whose character serves as the story’s moral conscience (early in the proceedings she spearheads a fight to open the shelter to more refugees despite the lack of resources, delivering a not-so-subtle message), more than matches his impact. William Abadie (of Emily in Paris) also makes a strong impression as a Frenchman who briefly takes the family in and begs them to take his daughter Camille (Nelia Valery de Costa) along with them.

Resembling the sort of B-movie fantasy adventure, with serviceable but unremarkable special effects, that used to populate multiplexes in the early ‘70s, Greenland 2: Migration is adequate January filler programming. The only thing it’s missing is dinosaurs.
