Oxygen might be Alexandre Aja's best movie to date.
It's a one man show, or in this case, a one woman show, as Melanie Laurent delivers a performance worthy of praise as an amnesiac who awakens in a cryopod and tries to figure out how she got there and how she can escape with the help of the AI assisstant MILO. The movie's plot is reminiscent of Buried, starring Ryan Reynolds, only this time we're dealing with a high-concept idea that cannot be mentioned without spoiling the movie.
What I liked the most about this movie is that throughout its entire runtime, it never once loses steam and is able to hold the attention of the viewer. Although it's set almost entirely in one location, the script always finds ingenious elements to keep the plot going and oftentimes it reaches that nail-biting tension the viewers expect from a sci-fi thriller like this.
Melanie Laurent is entirely up to task and she carries this movie effortlessly. Her character's discoveries about her past, present and future offer moments that showcase her immense talent of making us care for a character that we, like the character itself, know nothing about.
The direction from Alexandre Aja is never boring and he uses smart camera tricks to maintain tension and suspense. There's always a sense of engagement with the plot that Aja crafts masterfully, although some plot reveals are a little bit convenient and they come exactly when you expect them to.
Overall, I thought Oxygen benefits from an inventive and well-written script, Aja's tight direction, and of course, Melanie Laurent's performance, who carries the entire movie on her shoulders.
