Prime Video has just added a huge new sci-fi movie

The 2026 post-apocalyptic film is a sequel to a modern classic of the genre.

One day, John gets an automated message stating that he and his family have been selected for emergency sheltering. It turns out a massive interstellar comet is on a direct collision course with Earth and is set to cause an extinction-level event in two days.

Chosen for sheltering because of his work as a structural engineer, something vital for rebuilding society, the movie follows John and his family as they scramble to get to safety. This is as word gets out to the public about the impending disaster, leading to widespread panic.

If you do not want the ending of Greenland spoiled for you, turn away now as we get into the plot for the sequel.

Still here? We'll continue.

Greenland 2: Migration takes place five years after the conclusion of Greenland, in which Alison, John and Nathan (played by Roman Griffin Davis in the sequel) managed to survive by securing passage to an underground bunker in the titular Nordic territory just before the huge comet fragment struck Earth.

This safety is short-lived, however. When earthquakes destroy the Greenland bunker, the family is forced to return to the surface in search of a new safe haven.

What worked so brilliantly about the original Greenland was how it blended dark spectacle with believable human drama. At its best, the movie felt like an authentic depiction of the end of the world, as seen through the eyes of an ordinary family.

The general critical consensus for the sequel, which landed in US cinemas in January but had not been released in Ireland and the UK until now, is that it's not quite as successful at merging emotion and thrills.

That said, Migration has earned some decent reviews, thanks to its lead performances by Baccarin and Butler, its likeable characters and its now post-apocalyptic setting.

You can read a sample of these positive write-ups below:

The Daily Beast: "A sturdy continuation of this cataclysmic big-screen series, whose large-scale set pieces are rooted in the fear, anguish, and compassion of its appealing main characters."

The New York Times: "Though this sequel’s brisk plot hits familiar post-apocalyptic beats, [director Ric Roman] Waugh strikes them with immense force."

Vulture: "Greenland 2 rarely coheres as a successful disaster picture — especially when compared to the wonderful original — but we do wind up caring for these characters, which feels like some sort of small victory."

TheWrap: "These Greenland films may not always have a coherent point, but when they focus on the nuts and bolts of survival and the toll that surviving takes on these characters, they’re efficient, effectively crafted genre pictures."
