Other stories, however, are more puzzling for us. For instance, we've been surprised to read in feedback and emails that Alice in Wonderland attracts quite small children - even though the language is quite difficult sometimes. We are less surprised that adults like it, as it has so much interesting texture.
Some of the classic fairy tales are also quite hard to put into age categories. The Snow Queen is so beautiful that it seems to appeal to all ages. Even Snow White has dark undertones which can appeal to older as well as younger people.
I think that's why the classic fairy tales are so good. They do in fact appeal to all ages.
Still, Hina, thanks for the great suggestion and we will add some guidance for age, especially directing parents to stories for smaller children.
