Watching Song of the Sea can be a surreal experience at first, because the animation style is so different from what we’re used to in America or even from Japanese styles of animation that have become popular here. But, like in his last movie, The Secret of Kells, director Tomm Moore’s Gaelic-tinged style of animation goes from unfamiliar to bewitching very quickly. Moore deals in Irish and Scottish folktales, and Song of the Sea follows a young boy whose mother died giving birth to his sister. Years later, strange happenings involving fairies and owls lead the boy to believe his sister may in fact be a selkie, the Scottish version of a mermaid. The owls try to kidnap the sister, and the boy’s adventure to rescue and protect her leads him to magical places and characters reminiscent of Studio Ghibli’s most mystical stories.
