Oxygen: Netflix's new hit

Nothing like a thriller of people locked in suffocating environments without knowing how they got there to keep the viewer on the edge of the seat for a long time. On this occasion, the plot alibi enters the limits of science fiction, since from the beginning we perceive that the long-suffering protagonist of 'Oxygen' is not trapped in a coffin, a closet or a cell, but in an environment something more sophisticated. It is a cryogenization chamber assisted by artificial intelligence.

Our troubled heroine will try to communicate with her to avoid the innumerable obstacles that prevent her from going outside, from the hermetic closure of the capsule to the administration of sedatives, passing through the disconcerting communications with the police.

The main problem, of course, is that she does not remember how she got there or even what her name is, beyond specific flashbacks in which a hospital or a man who could be her husband appears.

All the weight of tension falls on an absolutely extraordinary Mélanie Laurent ('Inglourious Basterds'), capable of credible fits of anger, despair, rapid mental calculations to survive and anticipate the spectator's conjectures and, in general, represent a whole credible range of emotions with amazing ease and emotionality. Without it, 'Oxygen' wouldn't work as consistently.

It has a surprising and shocking ending, and that balances on the shoulders of a single actress
