The action and emotional depth of "Decibel" are both excellent for an action thriller. This film is a must-see for aficionados of the genre because of its skillfully developed characters, complex plot, and exciting action scenes.
The action-packed opening scene of the movie establishes the mood for the rest of the picture. The movie's strengths are its frantic, heart-pounding action sequences, which also feature excellent stunt work and special effects. The film also demonstrated how PTSD affects soldiers.
I saw the movie a few times, and although knowing what would happen, each time brought tears to my eyes. LJS's acting was outstanding. Every time they had a scene, his eyes would also show how much he loved his brother. I was devastated by the melancholy and breakdown he had in the submarine. Eunwoo's acting was exceptional despite the fact that he got fewer scenes.Raewon, the chief, made a difficult but necessary decision that, in my opinion, transformed his life, and this is basically how the tale was focused on him. How LJS lost his brother as a result of the choice of leaving some of his teammates due to a shortage of air LJS then targeted Raewon and his family as retaliation.The bombing scenes caused my heart to tighten.I thought the film was fantastic overall, and I left the theatre with bowled-over eyes.
