Choi Woo Shik's "Lab Manufactured Psychopath" vs. Kim Da Mi's "High-Functioning but not completely a Sociopath"

Before the whole world realized that South Korea can make a great movie after "Parasite" crushed it at the Oscars, S. Korea's film industry was already making good movies (that would have won awards already if those award shows weren't so biased). The Witch: Part 1 is one of these movies. It's a pure thriller with loads of action. I personally loved the movie but I'll still objectively review it.
Before watching this most of the korean movies I had watched were either rom-coms, mystery or action-comedies. The Witch was definitely a happy surprise. It was definitely not as dark as I had anticipated after watching the trailer but that didn't really disappoint me. The one thing that the producers could have improved was definitely the plot.

If you read the synopsis "10 years ago, Ja Yoon escaped from a government facility in the midst of an inexplicable incident by herself and lost all her memory.....blah blah blah.....A man named ‘Nobleman’ constantly roams around her, in addition to ‘Dr. Baek’ and ‘Mr. Choi’ who have been searching for her since her disappearance. Ja Yoon’s life falls into turmoil as they turn her seemingly ordinary life upside down in a blink of an eye", it basically explains the whole plot. It's just stretched over 2 hours with a lot of tense scenes and carnage but still, the whole movie is just that.
Despite the not very unique concept or the kind of boring plot, the movie holds it's own because of the great cast.
Kim Da Mi's transformation from a sick and confused high-schooler to a calculative killing machine was amazing to watch.
Choi Woo Shik's portrayal of a Genetically engineered killer with a goofy side (The Nobleman) was spot on and one of his best performances of all time.
Dr. Baek and Mr. Choi were characters with great potentials but limited screen time. Ja Yoon's bff Myung Hee did have quite a bit of screen time but wasn't really relevant to the story.
The Nobleman's posse of other Genetically engineered killers were entertaining by adding to the thrilling action sequences.
The ending was pretty open ended and left the audiences with a lot of questions as well as expectations from it's coming sequel. If you are fan of thrillers with fast paced action sequences or K-movies in general, this movie is a must watch.
