Both movies deal around a natural catastrophe that set the world into chaos. In both dramas the characters have to find a way to survive. The only difference is that Ashfall revolves around a volcanic eruption while The Calm Beyond focuses on tsunami due to a storm.
A young woman lives, hidden in simple view, in a destroyed Hong Kong structure after a tidal wave destroyed the city - A castaway on a concrete island. Her hidden presence is altered forever when a kid appears.
Watching one reminded me of the other. Both take place in a dystopian world where each has to survive. While The Calm beyond focuses on a natural catastrophe and the aftermath of it, Alice in Borderland pulls the people into a game.
