Not for the faint of heart

Rating: 9/10 (22 August 2018)

Wow, this movie intense. I knew nothing about this movie going in. Nada. I didnt even know the genre. So i was very shocked by how crazy it was.
Its violent and gruesome. Its dark and terrifying. I had to pause it periodically to breathe. Maybe im just sensitive.. but wow.
The acting is fantastic. The cinematography is top notch. It is so well done that you cant stop watching even though your body tells you to stop.
Something I personally consider to define a good movie vs a great one is how well they can hold a tone. A movie can have a lot of flaws, but if they can find a tone and stick with it or mold it as needed, then they know how to write a good movie. A movie can be fantastic in every way, but if the tone of the movie ever sidetracks, you can tell that they arent the best writers.
This is tonally one of the best films ive ever seen. They kept the intensity there at the right pacing the entire time. It never lost its tone. It never fizzled out or sidetracked. It keeps you on the edge of your seat the whole time.
Theres no traditional corny horror aspects whatsoever. Its a thriller to the utmost degree. No sound-driven jumpscares. Although there are some jumpscares, they arent the stupid sound-driven jumpscares. These are actually scary and well done, and not just meant to surprise you with a loud noise.
About the gruesome parts: Do not watch this movie if you can't take gore. The gore is well done though. Its as tastefully done as gore can be. Not corny and in your face. Its very realistic and they often use cinematography and lighting to hide it some so its not constantly overwhelming you. I personally am not a fan of gore, but it worked in this movie. The most ive handled is watching The Walking Dead. This is far far more intense and realistic.
