Greenland is a perfectly serviceable disaster movie that does exactly what it says on the tin: comet hits Earth, family tries to survive, everything is terrible and stressful for two hours.

The good: Gerard Butler's dad character genuinely cares about his family, and the movie doesn't shy away from showing both heroism and human ugliness during crisis. It's well-made enough that critics liked it.

The bad: It's exhausting. The entire runtime is anxiety and peril, with brief moments to catch your breath before the next catastrophe. The child separation scenes are genuinely distressing, and the 'worst of mankind' angle feels more exploitative than insightful.

The verdict: If you're looking for family movie night fare, keep scrolling. This is for older teens (14+) and adults who want a disaster thriller that will leave them feeling wrung out. It's not terrible, but it's also not particularly enriching or memorable—just competently stressful. The Letterboxd score of 2.9/5 tells you what you need to know: it's fine, but nobody's rewatching it.
