Since nobody wrote a review yet, i'm going to do it quickly. For those who watched the anime, the movie starts just after it and finishes the story of the Great Snow Sea. So, If you liked the anime, or just want to watch the conclusion of this history, to understand the reason the Great Snow Sea and the great Trees exists, this movie is a must watch, a kind of last arc big episode. In short terms, the Movie is a direct sequel of the anime. As of characters, scenario, animation, and all others things, it follows all the same as the anime. No surprises here.See it as a big final episode, and not a movie.
