This French animated film is extremely popular at our house-- we've rented it 3-4 times and checked it out of the library twice. I just have to give in and buy our own copy. Both my children love it, as do my husband and I.
It is the story of two boys who are raised by the same woman, mother to one and nanny to the other. They are like brothers when they are small and are later separated. Many adventures later, they are reunited and must get over their initial resentments to return to their former love for each other and to complete their quest for the Djinn Fairy.
This story, on its own, is visually stunning, and an excellent adventure tale. It has peril, magic, friendship, prejudice (overcome), persistence, and wisdom. However, it is so much more: an allegory about tolerance and believing in yourself and following your own path.
Watch it and fall in love.
