Query: What's with the lousy reviews?

My dad's a veteran of WWII. He bought a biography of The Andrews Sisters, and when I saw "Swing It" on the coffee table, I decided to start reading it. I then decided to order one for a friend of mine who's into swing music, and when he saw the negative reviews posted here, I was dismayed. I thoroughly enjoyed the book, which told me lots about this trio that I never knew, from their personal friendship with Lou Costello, to their abundant sacrifices for the war effort of the 1940s, to the reason they were so famous for squabbling. I also never realized that they recorded and performed through 1966 (who would've thought that The Andfrews Sisters recorded things like "Puff! The Magic Dragon" and "I Left My Hearty in San Francisco")? I thoroughly enjoyed the biography, and the pictures were great. And in regard to the bad reviews, I wasn't surprised to find that the e-mail address of the reader who wrote the "Yawn" review was "Nutloaf." That about says it.
