lots of amazing books that weren't around when I was a kid. Not just brillinat stories, but for you ger children, gorgeous pictures, and also dealing with themes that are very current.
I actually find most classics pretty bad reads. I have read out loud a lot of kids books to mine (now aged 15, 12 ad 10) and it is rarely the classics which grip their imagination. I think many of them write is a less direct or obvious way. There is a lot more inference expected from the reader. That isn't a bad thing in terms of comprehension, but it doesn't bring the story to life.
dcs school did a big push on the classics, and we had a suggested reading list. I am a governor, and I did have aquiet word with the head, after dd and I struggled through Huckleberry Finn, which is totally unappropriate for children, is littered with the n word, and is written for the most part in dialect 
Even Enid Blyton has a lot of things in it which need explaining (maids and servants etc). We have original versions of famous five, but after reading some of them with dc1, I did remove one book.
I actually think it is good for kids understanding of the world to read the original books, even when not pc. They themselves are often shocked/puzzled and ask for explanations. But some books really need to be read with cuation, and probably alongside an adult. The Famous Five book which I removed had a whole load of stuff about a circus in it. There was a 'pet' gorilla, and then a man who was constantly and casually compared to the gorilla. Yes, the man was black. I didn't feel that was appropriate even with explanations.
