Well acted with some excellent dark tones
Short review: Watching a film called 'Sleep' late at night seems like a challenging task. Luckily the film was so good that even watching characters drift off at that hour didn't make me too envious. I was really impressed with this film and what it managed to get out of the concept.
I loved that the film never felt safe. There was one scene involving a boiling pot. Now a lot of the time in most movies you wouldn't even consider the implication a possibility. Here though, it felt possible and I saw some hands go to mouths (mine included). This film is even made in such a crafty way that it is able to pull off and make exciting a PowerPoint presentation late in the film. Also the two lead actors turn in great performances that help elevate the film. This was a good one. 8.5/10.

It's gonna be hard for me to fall asleep tonight.
There is no jump scare, but how 'Sleep' manipulates my fear, uncertainty, and anxiety is something else. It's a kind of horror that I can watch without getting too scared, but I cannot go to sleep, thinking about the whole movie over and over in my head. The situation in the movie might seem extreme, but sleep disorder, noise between floors, and postpartum depression are very much realistic social problems and very much modern problems as well. They are almost tangible, and you hear about them everyday. Three things combined in the movie, the ending is not that extreme anymore, and it's scarier because it can happen to me, too.
How the director uses lighting and composition makes the movie more intense. Before the wife is affected by husband's abnormal behavior during REM sleep, lighting is shed in front of her face. However, once she starts to lose control of her reasons and mental health, the lighting moves to the back of her head, increasing the eerie atmosphere and highlighting the sudden change.

Sleeping can also be dangerous
Jason Yu's debut with his first film is truly satisfying, offering us an interesting and addictive suspense that overflows with tension with the intelligence of Korean cinema.
With a small cast where the main couple Jung Yu-mi and Lee Sun-Kyun steal the show, they manage to captivate with the true suffering that the situation that surrounds them brings and that their director knows how to handle in a balanced way between terror, suspense and touches of humor that lead us to have a truly effective film throughout its entire journey.
The greatest virtue of its script is knowing how to use the mix between the language of terror with a moving story of domestic life and the difficulties of marriage, and it does so with all that touch of a brilliant staging by its director and a BSO that sticks like the best companion so that everything fits together perfectly both visually, aesthetically and sound-wise.
Finally, it is worth mentioning that the film is not perfect, as we find a final part that is a little more abrupt than all of his initial work, but it does not prevent us from pleasantly enjoying what we are seeing.
An interesting bet that brings us a gratifying debut from a director worth taking into account, and that provides us with a fun Korean horror thriller that works with intelligence and simplicity at the same time.

Thriller Kind of Short on Thrills
Sleep come with some pretty good credentials and i was looking forward to checking it out. Unfortunately, it didn't live up to my expectations as i found it lacking in story development and unable to create the desired levels of tension one could reasonably expect from a film of this type. The performances were fine but there were quite a few gaps in the story with too little character development taking place. Also, there were too many examples of the characters playing either very passively or unwittingly to the point of losing credibility. The end of the film was not able to create anywhere near the drama I could tell everyone was going for and it felt a it forced. Sleep isn't all but still a bit disappointing.
Don't sleep on this film
This is a solid little Korean horror film, with a simple plot that's executed well. The acting from the two leads, Jung Yu-mi and Lee Sun-kyun, is top-notch. Jung particularly is great as the wife.
Where the film falters is in its open-endedness. There's a death early in the film that's seemingly significant for a few minutes, then the characters seemingly forget about it, then it's brought up again later in the film. And later in the film a character disappears then comes back without any real explanation. It left me wondering if perhaps the editor mistakenly edited out the scene showing what occurred between the character going missing and then popping up again. It just was bizarre. But some may consider this inexplicability to be a strength that adds to the spookiness. That leads me to the next point.
The great thing about this film is that, just like the characters, we're unsure of what's really going on here until the end. Is the husband mentally ill? Does he have a sleep disorder? Is he a ghost? Is he possessed? Is he acting? The film does a good job sprinkling in different possibilities throughout the runtime.
