All you need to know about this movie is that it's all focused on Rin and the Samezuka swim team. It's a retelling of Eternal Summer at face value, however, the extra scenes and emphasis on Rin and his swim team really made for this movie to be so good. If you're a Rin fan (like myself) you will absolutely enjoy this movie. The beginning actually brought me to tears because there are extra scenes of Rin's childhood when his father was alive and he was a happy little kid who admired his father. But then you also see that same child lose his fathertrying to deal with the pain that comes with it. You see him feel like he has to fill his father's shoes because he's the only son and male in the family anymore. You see how much it really hurt him and how hard he tried to stay strong for his mom and sister. How swimming was the most important thing his father ever gave him. These scenes were strong enough to break my heart. Even though we already know the details of Rin's past, seeing these extra scenes allowed me to understand why Rin became a sort of "antagonist" in the first season, the strength Rin really had and his unchangeable love for swimming relays.

All in all, the extra scenes really helped me comprehend Rin's character and see his side of the story. It made me realize why his friendships with everyone are so important, like why he became so upset that Sousuke didn't tell him about his injury or why he insists on swimming relays or who he exactly swims for. If you want an eye-opener on this series especially in terms of Rin and the Samezuka swim team, give this movie a definite watch!
