This film is really good. Park Chanwook made the perfect conclusion to a trilogy with Sympathy for Lady Vengeance. The three films work off each other beautifully, and Sympathy for Lady Vengeance is far from a disappointment.The acting is top-notch, with cameos from Park Chanwook's first two films intermingling with new talent. The directing is superb, not quite eclipsing Sympathy for Mr. Vengeance or Oldboy but coming quite close. Park's directing style is solid and distinctive; he builds off earlier films and ideas to give an air of intensity surrounding the most innocent of scenes.
SFLV cuts back on the violence and focuses on personal turmoil, a welcome change from the beginning of his revenge trilogy. My favorite elements of this movie are the use of flashbacks to tell the witty, yet complicated story, and that the film sticks to its theme of vengeance with a die-hard, unwavering dedication. The only thing holding back from a perfect score is a slow ending, one which is necessary to bring the trilogy to a close but still slightly treading.
All in all, this film represents a master finishing his masterpiece, should be viewed by everyone, and works perfectly as a separate film and not a piece of a trilogy. Violence is minimal compared to Park's first two films, but is graphic. "Sympathy for Lady Vengeance" is one of the few films that will make people cry not out of sadness but out of love.
