ARE SOME NEGATIVE ONLINE REVIEWS FAKE?

I try to not waste too much time reading online reviews.  There is a certain amount of wisdom in the collective opinion, but you never know who wrote an individual review and what their biases might be, so I think reading lots of online reviews is probably at best a waste of time.
When reading online reviews, I often get the feeling that the most negative ones are fake.  The first paragraph of the review that’s quoted in this Coyote Blog post is a good example.  Read it and see if you think it sounds fake.  There’s something about the way that review is written that is common among negative reviews, and makes me question the motives of the person who wrote it.
