Input: Consider Input: This screen protector is great.

Output: Good Review

Input: Consider Input: It's amazing to think that this is the same author of "The DaVinci Code", which was quite a good novel, with enough plot twists and action in it to keep you interested. The story line has potential, but too much time spent on meaningless conversations takes away from any excitement or drama. I did finish it, simply because of my love for Da Vinci, and although I am glad he didn't end up dead, his character could have been cut out without making an impact at all.

Output: Bad review

Input: Consider Input: The book itself isn't bad, but I won't buy anything from this publisher again. They shipped the first copy to me with many holes around the spine, and they sent a second one, which was still in bad condition after all this. This is just poor quality control. Amazon has always been good about this, so what you should do at least if it's going to be shipped, get it checked out by another customer who says it works fine.
Output: Bad review
