Last year I found this book and once I opened it I could not put it down. Bugliosi is excellent at bringing the details to life on the page. Not only do we get a first hand account of the trial, but he also explains much of the legal process in very clear and understandable terminology. I am now a fan of his work and will be reading everything I can of his.
Positive

All the features are nice, TV Guide worked (note that browsing and setting recording preferences is very SLOW), BUT when the TV Guide is downloading (all the time) or you are recording / playing from the hard drive you constantly hear a grinding sound from the hard drive. These guys must have used a cheap hard drive or something. I have the Amazon return slip on my desk......
Negative

My sense is that Baldwin wrote The Fire Next Time for anyone who had ears to hear, regardless of color or faith or gender. The emotional intelligence with which he speaks is riveting.

Positive
