Basic Science Class:

This movie is about Ruka, a teenager who meets two boys, Umi and Sora, who are adopted to live at sea. She gets intrigued by the mysterious phenomenon that happens with sea animals, Whales' songs, and the boys' role in the mystery.

[spoiler] The movie starts with a sport where Ruka hurts a bully hard and she is asked to apologise to the bully, or else she won't be part of a team. But she gets into a dilemma because she just retaliated for what the bully started. This scene in the movie looks pointless as she doesn't deal with it and this scene is not needed for the story for any reason. The movie gets to the actual story as she meets the boys. Exploring the plot, theme, and mystery through Ruka was well-written and made me intrigued to continue. The government experiments on the boys to find their aquatic abilities and proceeds to find the mystery of anomaly with the sea animals. This subplot also gets lost in this movie without any proper scenes.[/spoiler]

[spoiler] The movie at pre-climax starts to delve into explaining the creation of the universe, organisms, and sea. This movie just puts all scientific concepts of how the universe might have been created, the first life born of the Sea, and evolution; everything is filled with common elements and components, such as the mysteries of sea animals' gathering, sacrifices of characters, etc. What I expected was a movie like Luca, a much more grand story and theme; instead, it just has my school science book as a theme, mysteries, which should have been intriguing to enjoy the movie. The ending is just what I expected it to be. [/spoiler]

I watched this movie in English, Dubbing is fine. The animation was amazing as the undersea, beach, climate, and frames were good and admirable. The music was well used when the story failed to convince me to continue.

In conclusion, this movie failed to amaze me with its themes, mysteries, revelations, etc. It is not up to my expectations.
