I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: I guess these would be good if you had foot surgery and wanted to place something lose and protective over bandaging, but not for under a boot cast.

Solution:
Negative
