Based on a true tale, 'The Case of Itaewon Homicide' is a chilling movie. It is so realistic and well-made that you would want to believe that it's the real footage of the whole case that you're watching. Why the hell didn't I watch this sooner? It was so engrossing that I didn't even move for its entire duration. I was almost biting my nails all the way through the end. This movie has no romance and happy moments in it. It is tense when it begins and remains that way till the end. The direction of this movie is absolutely brilliant and the writing is top notch. The supporting cast was probably not as good as the main leads but both Jang Geun Suk and Jeong Jin Yeong were terrific in their performances. Jang Geun Suk was creepy and hot at the same time in this movie. This has to be his best performance till date. Overall, it delivered excellently. In spite of being tragic and having a dark theme, it made me smile several times. There were great arguments and defenses put forth while the oppositions accused each other. It was IMPOSSIBLE to figure out the answer. I admire the prosecutors and defendants. I think we almost always forget how difficult their profession is and this movie reminds you just that. I googled and was surprised to find out that after this came out, the victim's families actually appealed for a re-trial of the case. I can see why. It does provoke that thought in you. Kudos to the director! I will most definitely watch this movie again because it was so enjoyable. It also has great score in the background. It has never a dull moment and remains consistent. Give this a try if it sounds like it's the genre for you. I totally one hundred percent recommend it.
