And here we go again with Gerard Butler as apocalypse captain. Yup, wanna survive? Find that guy. For whatever reason, he seems to be better at this than your average post-Armageddon jackass.
First off, I love how the entire population of Earth is down to -I’m guessing- a few million dying people (the air is radiated. Why? How? Dunno. That plot will only surface when convenient). And with a whole planet to work with, they still fight one another. Easier to shoot a gun than push a plow, I’m guessing. I don’t fault the film for this … only for the inconsistencies. Is the air poisonous, or not? And if not, or not enough, why aren’t you working with the immense amount of land and resources that already exist. 99.9% of humans died five years ago; there should be plenty left to spare for the survivors, no? No. Humans. Pfft.
Engineer John Garrity (Butler), his wife Allison (Morena Baccarin), and now teenage child (Roman Griffin Davis) have lived in a Greenland bunker for five years. None of these people strike me as guys who have been stuck in a bunker for five years, but I’m not watching this film for the acting, clearly. So along with radioactive comet fallout – which, apparently, only affects parts of the planet—there is also increased seismic activity, which also doesn’t make much sense, but, hey, I’m not an Earth scientist and neither is anybody who made this film. I mean, for starters, how is most of Liverpool under water, but the English Channel has suddenly dried up? Please explain that one to me.
As the earthquakes rock the bunker, John realizes it’s time to escape; this becomes a now-or-never thrill moment. As does the deadly battle for watercraft to float to … elsewhere. Luckily, John is an engineer who knows how to fix survival bunkers and lifeboats alike. Unluckily, his son Nathan is a little bitch. I could take this act when Nathan was a 10-year-old in need of insulin, but at this moment, Nathan is the Peregrin Took of the afterlife, needy and useless.
Gee, just wait until the gang gets to England; I’m sure things will improve, right? The deal is that North America is still unlivable, but Europeans are enjoying a Hellscape of sorts. Seriously, this 
entire film is a strong argument for: “Why did we bother surviving, anyway?” Just know that there are perils many, and that’s before the armies of the apocalypse have a say.
Greenland 2: Migration is a frustrating film in that there’s a decent plot – a quest with clear goal and payoff—but the methods of getting to said goal and the heroes we have to follow are all kinda iffy. And the screenplay feels a lot like more like someone thought Greenland deserved a sequel than a natural extension of the original film. I mean, at this point in the history of this particular timeline, there must be millions of places to carve out the rest one’s life … but these guys only want to be in the one particular place and take the most perilous route to get there. Well, it certainly makes for an exciting story. Completely fabricated and unnecessary, but exciting! And it sure keeps the word “Greenland” in front of people. That’s really important because otherwise, like 340 million Americans during normal times, I’d never think about Greenland at all.
A small family survived in a bunker
And you’d think one might be a spelunker
But when apocalypse 2 came
They played the same game
And hoped their gambit wasn’t a clunker
