The Real Kiruna Crisis
If you want to make this movie more interesting for your kid, tell them that the town of Kiruna is actually sinking. In real life, the Swedish government is moving the entire city center, brick by brick, because the iron mine—which is the town's lifeblood—has undermined the earth so much that the buildings are at risk of falling into the abyss.
Disaster Tropes in a Different Language
The Abyss (or Avgrunden) follows the classic disaster movie blueprint: the expert who knows the danger is coming, the family drama that gets interrupted by a cave-in, and the heroic sacrifices. Because it's a Swedish production, it feels a bit more intimate and less 'superheroic' than a Dwayne Johnson disaster movie. Frigga, the lead, feels like a real person trying to manage an ex-husband and a new boyfriend while the pavement cracks open.
Should You Watch It?
If your family liked The Wave or The Quake (other Scandi-disaster hits), this is in the same vein. However, the audience scores are quite low, mostly because the CGI can be hit-or-miss and the plot relies on characters making some pretty questionable decisions to keep the tension high. It’s a 'background movie'—something to have on while you're folding laundry or scrolling, rather than a cinematic event.
