The website's critical consensus reads, "As stark and riveting as its cinematography, 'I, Olga Hepnarová' takes a sober, haunting look at the life leading up to a woman's horrific real-life crime.

[4] Glenn Kenny wrote review for The New York Times, "Anchored by a startling performance by Michalina Olszanska, the Czech film ‘I, Olga Hepnarova’ is an austere, hypnotic story of sadness, madness and murder."

He ends his review, "Early in the movie, Ms. Olszanska, a slight, narrow-shouldered woman, plays Olga as someone trying to recede into herself, slumping and looking to the ground as she puffs on a cigarette.

By the time of her trial, at which she pleads guilty and demands the death penalty, she is stiff, straight, defiant.

"[5] Writing for The Village Voice, Tanner Tafelski said "I, Olga Hepnarová is a bitter pill to swallow, focusing on the paradoxes of a misanthrope".
