Example Input: I just bought this book about a week ago. The first half of the book, which discusses issues such as how to implement business goals in your life, is very good. Then after that, there are various cases examples written by CEOs and others that help reinforce what they've discussed. Finally, there are several case studies with people who have become successful through their own hard work (i.e. one entrepreneur at a local store).
Example Output: Good Review

Example Input: When used in conjunction with a new water filter i no longer have to replace my Brita when we change filters. Very easy and fast to get the water flowing. You can switch them out more then once.
Example Output: Good Review

Example Input: Too little information on how exactly was done the capture of Idi Amin. Still it's pretty interesting that it has details about the process involved and that there are only some very vague mentions to him being captured.
Example Output:
Good Review
