Popularity, even with immense current relevance, is not the same as staying power.
The first Harry Potter book was published 14 years ago and it still has plenty of staying power. Look at the renewed interest with the last movie and now Pottermore and the eBooks. What is your definition of a classic other then 20 years or more that Harry Potter misses out on?
