Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Q: Good, sturdy platform for squatting under a barbell. Very firm. Laces are long enough to wrap around ankles, and back of shoe forms a fair notch to retain the laces and keep them from sliding up and off the shoes - would have been better had there been a rear loop. Shoes are better without the insoles because they put a spongy foam wedge under the heels. I replaced them with thin flat insoles from a pair of water shoes. One could cut the foam wedge and use the included insoles. There is no raised heel other than that foam wedge. They run true to size or slightly tight.

A: Positive

Q: You make it in rock and you think you can do it all. This book proves you can't. It is a truly poor excuse for a collection of haiku and it is particularly offensive because there are those who will buy it thinking it the real thing. Do yourself a favor and buy Higginson. You can look at this in a few minutes in the bookstore. It might be good for advanced classes in "don't let this happen to you!"

A: Negative

Q: What we have here is an academic paper puffed into a book.If one has the patience to wade through his tedious repetitions, condescensions, ax grinding, and self-congratulations, one is rewarded with the glimmer of a new idea. But that idea, recedes mirage-like, ever into the horizon. I don't know how I ever made it through.It's disappointing that Kingsley fails to locate his work within the context of Ganzfeld parapsychology, or even of Sumer, the source culture of the ancients. I was amused to find that despite what he believes to be his breakthrough insights, he is ignored by other scholars.Nice try, Peter, but you owe us much better. Next time, at the very least, give us a useful table of contents, a readable list of references, and an index.

A:
Negative
