This is fun. Much as I've admitted to liking Lev Grossman's books I don't think I've ever read any of his reviews greater than what is printed on the back of a book as a blurb. I did laugh, smile, roll my eyes, 'wink' when I came across The Lion, The Witch and The Wardrobe, not due to the quality of the book rather Grossman's literary ties with Narnia. All things considered, Times' list of 100 Best Novels was rather standard fair.
I don't read enough non-fiction to comment on this one.
I can't imagine there is much value to these kinds of list outside of those who only read a handful of books a year, but they are still fun to look at.
