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.

Ex Output:
Positive


Ex Input:
This is being written mostly in protest of the re-print. The stories in these series were always a little dull. But the art, the art was fantastic, and now they've taken it away. I dont have my old copies any more and now the old books are going for outrageous sums. I wanted to get these books for my kids someday--not any more.

Ex Output:
Negative


Ex Input:
It is absolutely unbelievable this woman IS a therapist, by reading her book, she NEEDS one. She relates to clay more than to children or people. Whatever she was looking for in an Amish community, she never found it and translates that to the reader. Don't waste your time with this very poor read.

Ex Output:

Negative
