Input: Consider Input: I've read many books on Hollywood, including Kevin Costner's book, which is well written.

Output: Good Review


Input: Consider Input: This "biography' should only be offered via e-book (or another digital source).

Output: Bad review


Input: Consider Input: I am returning this book, because the title is misleading and in fact it is not by Tom Waits but his former group Dead City Ramblers. Although this book would probably rate a high for people who do NOT know about Dead City, it does provide some nice pictures of Tom's life as an adult. For those who are interested in knowing more in-depth info on what happened to him, like you wouldn't find anywhere else, then get another book. This one just doesn't even come close.


Output: Bad review
