One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: As a teacher, I've enjoyed using this book over the years in my reading program. Imagine my excitement when I learned that the book is on audio. Please understand, the book is worth ten stars, and I really love the story. It is very well written, the characters are fleshed out and believable. BUT... the audiobook is a great disappointment. It is read by the author with a full cast. Somebody forgot to tell Mrs. Phillips that she is from England, and, therefore, has a british accent. The woman reading her part sounded like she is from Iowa. Almost from the beginning I'm listening to audio and I'm going HUH!? This is what happens when you don't pay attention to your own production. I'm amazed that Winthrop allowed this lemon to get out, especially since she is reading on it. Go Figure!
Solution:
Negative
