It is a violent and bloody film. It's scary from start to finish and keeps you waiting for what will happen, the way people die is very ruthless and bloody. Seo in guk did a great job with his acting, it was phenomenal and exquisite, I was able to enjoy his character too much, seeing that wild side of him is very gratifying. The cast did a great job too, I congratulate the director for this great movie, I am glad that it has been widely accepted and loved both in Korea and abroad, it deserves many awards, this movie is not suitable for anyone because its genre is very violent, I recommend it 10/10.
