Well uf you love seeing action and stunts then ballerina is a must watch. But after watching crime kdramas this movie didn't reach my expectations. The storyline wasn't that captivating and the movie was just full of stunts. It did focus on the realism but the story should have been improved. It just shows the urge of revenge and nothing else. The movie isn't that fulfilling and lacks other traits. Definitely not worth rewatching. Being a crime,action film it didn't have much plot twists and if compared to other films it has many flaws. This is my personal opinion.
