Colorful and highly saturated visuals often appear tacky, but "Deep Sea" is not one of them. The flow of various lights and watercolor hues, creates a strong visual impact. Each frame is like a world-renowned painting that immerse audiences in a beautiful world. The last twenty minutes of the story are tear-jerking, as many details and clues from the earlier part of the story suddenly become clear. Although I haven't experienced the same thing, I've heard from friends who have had similar experiences and can empathize with their tears. This is a story about self-healing and growth, and it's been a long time since a film has touched me so deeply. It may be difficult for young children to understand, so it's recommended that parents watch it with them and guide them through it. I strongly recommend this work to all adults, as it provides a delightful visual experience and provokes empathy and insightful thinking.
