I'm not a fan of the crime writing genre, so I require more than some blood and guts and a few nasty frights to make me speak highly of a crime novel. Unfortunately, I cannot speak highly of From Potter's Field.I know more about dogs than I do about forensic medicine, so it makes me suspicious of the novel's factual integrity when I read that a murderer's eyes are "as pale blue as a malamute's", when in fact (according to the Alaskan Malamute Club of America), a malamute's eyes MUST be brown, never blue.It also made me laugh to think that all the crime agencies (and the media!!) in the USA would be completely ignorant regarding the closest relatives of the country's highest profile serial killer. Although if the good guys had known some basic details about the killer's family tree, Dr Kay would have been left twiddling her thumbs, so I suppose I should quit complaining.Well, I read the book right through to the end, and it kept me amused, so I have to give it one star.

Ex Output:
Negative

The old saying hollywood never lost money underestimating the intelligence of the american people really hits you in the groin with this head shaker of a release.While the orignal classic rollerball hasn't even gotten an anamorphic dvd release, let alone a blu-ray!

Ex Output:
Negative

I found this book to be an honest look at the world of hockey goaltending from mites to the pros. My son, who is a youth hockey goalie, enjoyed reading Robb's history and hockey philosophy. A good book for all hockey goalie parents, especially those who are new to the goalie world.

Ex Output:

Positive
