I remember seeing this one when I was seven or eight. I must have found the characters round, because they left a impression in my mind that lasted for a long time after the end of the movie. And the ending, now that's sad, well... for a 7-8 year old kid.
I had the opportunity of seeing this movie again lately, and found that the plot was too simple, the character, two-dimensional... I guess it's the kind of movie that you can only with the innocence of a young child... Pity...
I recommend this one for all you parents with small kids... ( I saw it in its original french version, so I cannot tell you whether the translation is good or not.)
