Question: Stay Clear of Lonely Planet . A hopeless mess of headlines and confusing comments, very little structure. No rankings of what you should see and do, no pictures, no useful restaurant and hotel recommendations. Endless yatter about nothing makes this a boring read with almost no real content. Absolutely worthless on our Japan trip to Tokyo and Kyoto. This is not the first time we have been disappointed by Lonely Planet. They cater to backpackers only, usually looking for the cheapest accomodation and meals, and with no value added for the traveller who is short on time but still wants to make the most out of his/her time. We ended up buying the Eyewitness Guoide which is fast and easy to use.

Answer: NEG

Question: Conrad's Greatest Novel . Nostromo is simultaneously a great political novel and a great psychological novel. A large part of Conrad's achievement is his fusion of these 2 elements into one seamless narrative. Nostromo describes the penetration of a Latin American country by European/North American capitalism and the ensuing revolution. All the characters in Nostromo are engaged in the intensely political acts carrying the plot forward. Conrad based his narrative on a considerable amount of research on contemporary Latin America and the articulation of the plot elements is elegantly realistic and gripping. The psychological elements concern characters' motivations for their acts. A recurrent ironic theme is that important characters are driven to act by motivations that have nothing to do with political objectives or economic gain per se. Unlike most of his other novels which offer a psychological portrait primarily of a single character, Nostromo features several characters whose motivations and actions are explored by Conrad. The focus shifts from character to character is a way that consistently advances the plot, a brilliant piece of formal construction. Finally, Nostromo features some of Conrad's best descriptive writing. Because of the complexity of the plot and characterization, Nostromo is not the easiest of Conrad's novels to read. Nostromo is ultimately well worth the effort expended

Answer: POS

Question: Dumb . This is one of the stupidest books I have ever read. The main character, "Fred" the mermaid, is a mass of neuroses. She's bitchy, snide and her responses to the most simple of events is weirdly inappropriate. In the very first scene, this 30 year old ph.D stumbles across her parents having sex and completely freaks out, so much so that she violently (but oh, so amusingly...) attacks them both. Time for little Fred to grow up, I think. The mystery is too easily solved and the men in her life, both instantly, and for no apparent reason, falling in love with her, are simple stereotypes of the gorgeous but smitten male. The first in a series, It seems likely that she'll soon be having a lot of sex with both of them; and simple, brainless pornography is about the best I can hope for from this ridiculous book
