As this film opens a woman wakes in an airtight medical cryogenic chamber. She has no idea who she is or how she got there... or even where 'there' is. The unit is controlled by an artificial intelligence called MILO; this informs her that due to an unspecified problem she is rapidly running out of oxygen. If she is to survive she will have to recover enough of her memories to learn about the situation she is in... and avoid some of MILO's attempts to make her little remaining time more comfortable.

Going into this film I'd say the less you know the better; there are some good twists and it is best one learns facts at the same time as our protagonist. The film is, apart from a few brief flashbacks, set almost entirely within the cramped pod; this gives an impressively claustrophobic feel to proceedings. The more we learn the greater the sense of hopelessness. Mélanie Laurent does a really fine job as our protagonist; you can feel both her anguish, fear and occasional optimism as situations change. The inside of the pod is well designed; large enough for some movement but not enough for full movement. Overall a solid film for sci-fi fans who don't demand lots of action.

These comments are based on watching the film in French with English subtitles.

If you are claustrophobic it may be a good idea not to watch this. If you like movies that do a lot with very little (at least seemingly little),you will be entertained. Aja does another movie that is in a tight place .. even tighter than the last one he did with the crocodiles (or is alligators? I always mix those up).

Amazing performance by the lead actress. Say what you want about him or his films, but he really knows how to do psychological horror ... this is well thought of and makes sense overall if you take the Science Fiction parts into account. We're not anywhere near freezing people for their safety ... for whatever reasons.

The guessing game is there and you may like where this heads or be appalled/annoyed by it. I dug what this did - another good Aja then.

Both movies above may have influenced this science fiction film, not my taste but worth seeing for those in search of this kind of feature. It is more than predictable but Melani Laurent is awesome in this film. The oxygene issue in space has already been evoked on netflix platform a few weeks ago in STONAWAY. Is it a coincidence? I won't say more,because I repeat, this stuff is not my taste. But I have seen worse as time waster, though a bit slow...
