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

I only recently read this so called masterpiece. I even went do far as to order the special complete edition from the Science Fiction Book Club. Even though I got through it I cannot believe all of the outstanding reviews and awards this series has received. No characters, no science, no mystery (who couln't figure out the identitiy of the Mule?). In addition the story is basically one of the collapse of the Roman Empire. It probably could have been rewritten replacing historical language instead of spacefare and it would not have mattered in the slightest. The only science fictional element was Psychohistory which is not developed at all due to the nature of the plot. If this is a classic, I shall stick to more obscure and worthwhile reads. Blech.
Output:
Negative
