If someone loves (or loathes, for that matter) every single book they read, I recommend to take their reviews with a grain of salt.
Judging a book merely by the stars it received is plain superficial. I suggest to read the review and ignore the rating.
Free books for bloggers do not translate into dishonest reviews. Exceptions to the rule are few and far between.
Whether a review should be short or long is entirely up to the reviewer and a matter of personal taste. It's about the content, not the word count.
It is not ok to affront or attack someone when their views on a book collide with your own opinion. We can't all be of one mind, so live and let live.
What's your take on my reviewing wisdoms? Anything you'd like to add? Please share.
