Example Input: I haven't done any serious studying for my exam. This will be the first time I've ever sat at a exam after watching a TV show and looking all over this book before I go into each section, trying to find anything. I can almost get through it...
Example Output: Bad review

Example Input: The title of this item is very misleading. I have found nothing more than "basics" to be offered in the recipes. It was not what I had expected from a new book. A cookbook that would teach you how to do all kinds of things for your family, but most importantly - recipes where there are no preservatives. There were a few things, such as a banana bread recipe and one on my favorite dessert, carrot cake recipe. But those weren't worth paying for. I'm sorry I bought it.
Example Output: Bad review

Example Input: Don't buy this cheap garbage from China, not worth 10 cents. You will be disappointed. I am going to try and return it. My guess is the manufacturer has had a run of bad units. Just go somewhere else with your camera needs. The good news is, it takes standard SD cards (I use SanDisk Ultra 8GB cards), which are readily available all over. That way you can take pictures where ever without worry if someone steals them- just get another card.
Example Output:
Bad review
