Q: 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.

A: Negative

Q: I used this program for my science class. My students loved it! They learned some interesting facts, saw damage from earthquakes we talked about in class and never once did I hear that it was boring! Can't beat that!

A: Positive

Q: Probably the most best album that will be released this decade. It has great significance in a post-9/11 world. M.I.A. has no qualms about mentioning bombs, guns, terrorists and racism in her songs. Every track stands out, the previous release tracks 'Sunshowers' and 'Galang,' probably some of the best tracks of 2004, are overshadowed by 'Pull Up The People' and 'Bucky Done Gun.'M.I.A. is truly is TuPac of the third-world.

A:
Positive
