This is a tremendous film, and a beautiful DVD. My son wanted to watch nothing else for the last four weeks, his enthusiasm for it was immense.
This movie is nothing like your standard cartoon offering - the story is simple and pure, the animation is crisp, the music is enchanting, there is no attempt to dress-up the story, and the representation of West African culture is pretty fair.
If you can (or your kids can) understand any French then try to watch the movie in its original language, the songs and the dialogue work much better, plus the accentation of the English dubbing is questionable (while all the accents are African they span the whole continent so it sounds very "dubbed").
The DVD pack comes with a bonus disk which is interesting and fun, but only in French.
All in all I cannot recommend this more highly. This is a great movie that kids will watch over and over again.
