I found a hidden sci-fi gem on Prime Video: the movie Radius from 2017.
The premise is that a man wakes up from a car accident with amnesia and an terrible involuntary power: any living thing that gets within a certain radius of him dies instantly and collapses on the ground.
Going into it I was skeptical that a full story could be built around such a severe constraint. Not only do we get a full story, but we get a story that's much more layered and cohesive than the simplistic fight-or-flight montage I was half-expecting. The story brings with it some complex ethical dilemmas and there are some correspondingly complex feels at the end.
There are a lot of little issues I could nitpick about, but at the end of the day it's worth seeing regardless!
