DEEP on Netflix is a new Sci-Fi Thriller from Thailand. Unfortunately, it’s both rather slow and unengaging. It’s about sleep deprivation in the name of science, but it feels off. Also, the English dialogue is so cringey – but not from the Thai actors. Read our full Deep movie review here!

DEEP is a new Netflix Sci-Fi Thriller from Thailand. The concept sounds strangely familiar and is obviously made to have a universal appeal. Unfortunately, this also means pulling away from everything that could make it feel like a Thai production.

Well, except for the English dialogue included. This is so grotesquely terrible. Especially the lines spoken by the “German doctor” in this storyline. He speaks so slowly that it would be creepy if it didn’t just feel false. I am fine with Thai actors having an accent while speaking English. It’s the rest of the English dialogue that really irks me!

Do not fall asleep

The main plot in Deep has to do with experimenting on insomniacs to extract something called “Qratonin”. This is supposedly the exact opposite of melatonin, which is the body’s own “sleep drug”. In order to extract this, a group of medical students agree to be part of a medical trial for the German pharmaceutical company “Weimar”.


There’s already a Thai movie on Netflix called Ghost Lab which features experiements >

Basically, it’s all about sleep deprivation in the name of science. It just feels off because every scene showing these student battling the urge to sleep (strange for insomniacs, by the way) have very strange reactions. They’re always about to fall a sleep in the middle of something instead of when they’re not doing anything. Usually, sleep creeps in when you’re not staying busy.


Watch the Netflix movie Awake where you can feel the characters’ need to sleep while not being able to >

I’ve certainly never been about to topple over and go to sleep while playing basketball. I have, however, battled the urge to sleep while watching a bad movie. Speaking of this, I am sorry to say that Deep is a rather slow and unengaging movie. The actors are given flat characters to portray and it is way too slow-paced.

Deep – Netflix Review – Thai Sci-fi Thriller

You can watch the Thai movie Deep on Netflix!

The Thai Netflix movie Deep has a whopping five (5!) directors attached, which is a huge red flag. The directors are Sita Likitvanichkul, Jetarin Ratanaserikiat, Apirak Samudkidpisan, Thanabodee Uawithya, and Adirek Wattaleela. On top of that, there are six screenwriters on board as well. Four of the directors along with Kittitat Nokngam and Wisit Sasanatieng.


If you’re curious about some of the better Thai productions on Netflix, then there’s the supernatural Netflix thriller series The Stranded (read our season 1 review here). Also, the visually stunning horror movie Inhuman Kiss (review here).

I always like checking out Asian genre films on Netflix. Usually, you’ll stumble upon something fresh and interesting rather often. Unfortunately, Deep is not one of those times. But hey, maybe that’s just my experience. If you’ve enjoyed other genre films from Thailand, then you should definitely give it a shot.

Deep is out on Netflix from July 16, 2021.

Chronic insomnia becomes a deadly quest for survival, when four medical students, Jane, Win, Cin, and Peach, are lured to participate in a secret neuroscientific experiment called ‘Deep.’ So, what’s the catch? If they stay awake, they make a fortune, but if they fall asleep for more than 60 seconds, they die. When ‘Deep’ begins to take a horrible turn, the four insomniacs, along with Jane’s younger sister, find themselves in a desperate, high-stakes gamble that will ultimately determine their fate.

I write reviews and recaps on Heaven of Horror. And yes, it does happen that I find myself screaming, when watching a good horror movie. I love psychological horror, survival horror and kick-ass women. Also, I have a huge soft spot for a good horror-comedy. Oh yeah, and I absolutely HATE when animals are harmed in movies, so I will immediately think less of any movie, where animals are harmed for entertainment (even if the animals are just really good actors). Fortunately, horror doesn't use this nearly as much as comedy. And people assume horror lovers are the messed up ones. Go figure!
