What is The One about?
A sheriff's deputy fights an alternate universe version of himself who grows stronger with each alternate self he kills.
Does it have a happy ending? (spoiler-safe)
It leaves the ending open to interpretation.

A relentless fight for survival unfolds as a man battles his own alternate-reality doppelgänger.
High-octane and pulpy. A full-attention watch at full speed. Emotionally it carries some weight.
Streaming on Prime Video, Kanopy (free), Hoopla (free) and Tubi (free).
For a PG-13, this one goes further: brutal violence. Beyond that, no sex or nudity and mild language.
Our estimate: fine from about 16, higher than the PG-13 suggests, because of the violence.
