Input: Consider Input: Extremely Disappointing . Although this book would appear to have a lot of promise, it ultimately fails. Like Mr. Taylor's self-proclaimed "Certified Professional Landlord" title (Fill in your name on page 218 for your own bogus certification!), these phony forms are imaginative but have little to no legal standing. Worse, Taylor apparently has little respect for his tenants. One form, the "Tenant Late Rent Warning and Excuses" form ("To be given to new, renewing, and late tenants.") asks tenants to mark a box as to why their rent was late. Sample excuses: I was mugged. "You didn't come by when I had the money," "I didn't have a stamp," "I'm dead." A chuckle for a landlord, but also a cynical and unprofessional suggestion. Taylor's advice on handling phone calls from prospective residents is even worse - he promotes using a hard-sell interrogation on the first contact that seems destined to drive away prospective tenants. Anyone with intentions to do good business would be well served to get more professional advice than this extremely disappointing book

Output: NEG

Input: Consider Input: A must-read. Period. . I recently read Berlinski's book as well as Bawer's "While Europe Slept" and "Anti-Americanism" by Jean Francois Revel. These are very important books in that they shed light on the mythology of the American Left, according to which Europe (Western Europe, that is) is the Promised Land. Since they detest America, they need to find some model to emulate. Well, on closer inspection Europe is not it. Today's Europe had been left hopelessly behind. It lives off the corpses of the past, and having been given a sense of security (by the American foreign policy and its military might) and illusion of prosperity (originally spawned by US economic aid and today dependent on US spending power!), they feel superior to the US. Anyone who ever debated angry Europeans will quickly discover that the superiority is really a reaction to their profound inferiority complexes. Disregard the one-star reviews. An M. McDonald below claims that the book is "short on facts"... This from a guy who claims that Germany is the world's largest exporter... Forgot to mention though that it's the larger exporter of MERCHANDISE. If you add services, the US exports are at $1.15 trillion vs. Germany's $893B. And, thanks to diversification, the US is less vulnerable to global economic slowdowns. McDonald's is wrong. He's wrong about public education too: Europe's schools are "vastly superior"?...Does he have any idea what goes on in the schools of Paris, London and Rome?? he says China not seen as a threat to EU? Anyone who's been to Italy recently, with interests going deeper than gelato, surely must have seen numerous campaigns against Chinese textile imports. My bet? In 5-6 yrs we will be buying superior quality suits made in China for $500 vs. Zegna's $1800 outfits. Indeed, nothing to worry about. Etecetera, etcetera. Read this and the other books I mentioned so you can be immune to and be able to eloquently respond to this type of leftist pap

Output: POS

Input: Consider Input: Worst travel book that I have ever read . OK, Buenos Aires is a spanish speaking city; but when every other word of a sentence in this book is full of spanish, it makes the book very very hard to read!!!! "Facts about Buenos Aires" is nothing but that, a list of useless facts emblished with unnecessary adjatives: "...something that differentiates Buenos Aires' people from their North American or European cousins - a striving melancholy and a desire for something greater." HM??? What we travelers want is an easy to read book, not a trash compactor, TOO much information one after another in a paragraph with vague english + foreign words is a waste. The few pictures in this book don't do justice to the city, take a look at any "paris" book out there, your response is usually "WOW, I would like to go there." after reading this book, it's like "hm... why do I want to go there?" Choose a different book; don't waste your time and money
