Almost everyone has seen a low-quality book critique - in lots of magazines that is virtually all that will get published!
A number of the awful types are in fact book summaries. They tell what exactly takes place in the book without having consideration to the entertainment of the target audience. In preference to tantalizing by incorporating some key points, analyzing the book, and permitting you to delve into it should you wish to, these people in fact destroy it.
Whilst it is simpler writing this style of book review, it's also bad writing.
