What seems to me is that the person who wrote the review at amazon.com has made up his/her mind right from the start.

If you ask a person, whoes profession is buisiness, to say what they think Quantum mechanics, they'd probably tell you its a bunch of mumble jumble in sceience which has absolutely no means of application and value.

If you ask a baby boomer who has never used a computer before to tell you about computers, they'd probably tell you that computers are just a fancy typing machine which does nothing but drains your pocket book and takes up space on the desk.

If you ask a person who hasn't even given photoreading a chance, as in amazon.com, they'd most likely tell you its just a ploy to scam people of their money.

The main thing im trying to stress here is that you cant judge eveything using an analytical standpoint. Sometimes you need to have a leap of faith; look beyond the sums of the facts.
