See, I devoured those as a kid. And I ended up reading very few of the originals. So I haven't allowed them in my home, figuring that if a child isn't ready for the original, well then there is plenty of other good literature for them to read at their current reading level.
Here's a good update, though: dd asked me to put the original version on her Kindle, and I know she at least started reading it. She may have been influenced by her sister, who is re-reading the original right now.
