[EX Q]: I had been planning a trip to the Galapagos Islands, and this guide was required reading by the tour group guide. The guide is thorough, providing information of interest and useful for all travelers traveling among islands, but the format of this book severely detracts from any pleasure of seeing them. There's an interactive CD-ROM provided which allows you to see photos that were previously in the book, but not the whole trip. Additionally, there are many grammatical or spelling errors.
[EX A]: Bad review

[EX Q]: I'm a fan of everything about this show. It is entertaining and makes you want to see what will happen next.
[EX A]: Good Review

[EX Q]: This book would be worth buying if it were listed in a library donation program. The author has made many wrong assumptions about how Christians think and what makes them believe as he presents them. He is clearly an atheist, not merely agnostic. It appears to me that his beliefs are influenced by certain influences such as Roman Catholicism or evangelicalism, but there doesn't seem to have been much research conducted into the subject.
[EX A]:
Bad review
