Example Input: My cat loves these. A little spendy, but worth it, even at $6/bag. She likes them because they are soft and have no rawhide in them. One of my cats is very picky with food. I thought she wouldn't like these, but the first time we opened a bag from this seller, she licked off all the bits that were left.
Example Output: Good Review

Example Input: The book really didn't hold my interest. Not one of Grisham's best books. Hard going at times,and almost nothing on the death penalty. Too many things that did not make sense. Would have been better if he had concentrated on just ONE murder.
Example Output: Bad review

Example Input: This is one of those simple, yet helpful devices. I've never used one before, but after my last knee surgery, it helped immensely for just about everything. It's lightweight, easy enough to move around. It easily wraps around the knee, giving you that extra support.
Example Output:
Good Review
