Query: Disappointing for a big fan of Genius by Gleick

I loved Gleick's biography of Richard Feynman, "Genius". So my expectations for this book on possibly the most important mathematical and scientific figure were very high. I was somewhat disappointed. This biography is a little short and seemed to need a little more meat. I did not feel that truly made the reader understand the importance of Newton's accomplishments. I thought there was a little too much on Newton's forays into other fields like philosophy, etc. Also a little too much on the political fights with other scientists and mathematicians.
