Example Input: I am a fan of Jack Reacher books, but this is the worst one. Usually he doesn't bore me as much with long winded dialog that takes up pages, and this time not even close. The last 20 pages or so were pretty good when it got to actual action. Not recommended.
Example Output: Bad review

Example Input: This product had no impact on our mouse problem,which was becoming less and less of a problem. We have been using this for over 3 months, maybe it has not done its job, but at any rate, we aren't convinced. The problem is, mice are attracted to the food in my kitchen. Mice cannot see through metal foil, so what works wonders for them would be useless here.
Example Output: Bad review

Example Input: It takes a lot of strength to take my vitamins with all the pills and liquid. I just bought this at CVS in their vitamin section. It's more than twice the cost. The taste is pretty bad. Maybe some people like it, but it does not appeal to me personally. I've also lost faith that anything good or natural will actually work for me. I'm going back to pills. You may love these, though, if you are one for chemical concoctions. Or maybe a multivitamin. This ain't it.
