My boy also cried the first time we saw the film, when the mother vanishes in the sea! He just sobbed with tears for like half an hour, crying for "mommy!" even though his mother hugged him the whole time. But he was probably 3 then... Now at 5, he loves the movie and every time we watch it, he says to his little sister - now is the sad part, but don't cry, later they will find their mom, who is a magic seal!

If you enjoy this style of animation (I immensely do!), then you must see Tomm Moore's other movie - The Secret of Kells! Oh, and another one that's a visual feast and full of lessons to be learned is Mune!
