The second scenario is reminiscent of any number of disaster and / or science fiction movies about flooding, apocalypse or dystopia (When Worlds Collide, Rudolph Maté, 1951; Children of Men, Alfonso Cuarón, 2006; Waterworld, Kevin Reynolds, 1995): if you approach this movie expecting something like that, you’re going to be disappointed, because although that element is very much present in the film, it’s little more than the backdrop.
The “Children of Men” (2006) inspirations are apparent and effectively realised, creating a dystopia that’s most terrifying in how jaded people seem to have become by the despair of this new world.
