Output: Positive

Input: Consider Input: I have only wore these boots a couple of times, so I may be reviewing them too soon. As other reviewers have stated they don't seem to need a break in period, but there is a certain "learning" period. I say this as a person who literally has worn nothing but tennis shoes for years. The learning is getting used to the extra weight and bulk on your feet. I bought these to be a part of my "bug out" plan. I will soon be going on a real hike on rougher terrain to see how they feel then. Plus until I have put many more mile on them to see how they hold up I can't say for sure how many stars they deserve. I give them 4 for now and assuming 200-300 miles from now they are still in good shape I would change it to 5.

Output: Positive

Input: Consider Input: Thank you, Erika Vause, for your positive review! I absolutely love this book! I had heard of this novel, but never considered reading it because the plot simply did not interest me. Then we read it in our academic English class (10th graders) and I was absolutely astonished!! Not only by the magnificence of the book--its themes of guilt and redemption are powerful and heart wrenching--but by the ignorance of some of my peers. It was obvious that their dislike sprung from the fact that they did not understand it! Please, please--read this book! You will not be sorry! I promise.
Output: Positive
