This is a story that will see one person contained with little chance of escape in the similar style as Buried, only with the sci-fi twist to everything going on within the film. The memory loss side of the film does show how technology has created a chance for people to try and figure out what has happened too. The story does have the twists along the way, even if the final reveal does become clear early on in the film.

ThemesOxygen is a sci-fi film that is filled with the horrors of being trapped in a cryogenic chamber, it gives us the race against time, with the real time feeling to everything going on, while using the technology that shows that certain factors could be taken away from the human factor. The special effects are amazing in the film, with the chamber having different reveals to what we get to see in the film.


Oxygen is a wonderful claustrophobic sci-fi horror, which is filled with tension throughout the film.
