Based on the novel 'Initiation Love' by Kurumi Inui, Lee Gye-byeok's 'Sweet & Sour' is well-constructed and well-acted, but lacks deeper and moving emotions when it comes to its narrative. The writing feels repetitive and stretched out at times but delivers home the point. Though rushed, the movie's twist offers a powerful ending that may stick with some viewers and reinforces the thoughtful themes displayed in the film.
