I loved them as a kid. I also loved that BBC adaptation - if not for the Tom Baker version of Puddleglum in The Silver Chair.
But when I have tried to revisit them, it has always been painful. I think I need allegory AND character development from my fiction now, and there is no going back.
My kids have rejected them whole heatedly. I think that is because they read HP first. Which - while not great literature, is certainly pretty well shored up on all the basics of fiction. Unlike Narnia - which was pretty sketchy on characters with depth, and any sort of plot intrigue. I think HP level set them well above what Narnia could hope to deliver.
Still I am glad I did absorb them, if not for just the knowledge of pop-culture it affords my present day reading. And it gave me an early love of allegory and biblical mysticism.
Thanks for posting the critique panda.
