Input: Consider 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...

Output: Bad review


Input: Consider Input: A very handy tool. One of those items that could have been improved upon.

Output: Good Review


Input: Consider Input: I really do have nothing to say about this book. It was just another book that told me something new but never did anything for me. If you are looking to see the real story of Mr. Ray then get The Long Walk. He goes into great details about how he lived on his land and with a few exceptions like the chapter where his son found out who killed him, it left alot out.


Output: Bad review
