I highly recommend the book The Blind Side. Not only for the story of Mchael Oher's and the Tuohys, but for some great football stories. If you're a fan of the game at all, you'll love it.
IIRC, the movie was based on only one chapter of the book.
You are right. The book was fantastic. The author taught us a lot about football. Bill Walsh vs. Bill Parcels. Throw in Lawerence Taylor forming the need to protect the blind side. Then there was the funny part. The big black kid was a fish out of water. The funniest line was from an out of stte relative: “I’m on my 3rd beer. Who is this big black kid in your family Christmas picture?”
Didn’t bother to see the movie. Sandra Bullock does not look like someone’s mother. It probably emphasized racism more than it should.
