Bests & Worsts Reviews from Amazon

I was hoping that this would be a good addition to my library, but I was quite disappointed. I understand that it's meant to be a short overview, but it feels a touch too short and almost unfinished. In comparison to books by Carl Sagan, all of which I've read, this pales in comparison. Neil is not nearly as likeable, his ego shines through in a number of passages. This feels less like a chat with a friendly, intelligent friend and more like a monologue by a college professor that loves himself too much.
