Given an English language product review, determine if it is a Good Review or a Bad Review. A good review is one where the product's review has positive tone and Bad review is one where the tone of product's review is negative.

I was really hoping that this book would show me more in depth about the author's life and career, but it only touches on some topics. It just left me feeling rather flat after reading it. She talks a lot of talk when really she never does much. It's nice to read about her work at first with all the interviews, etc. But then as you move into the last chapters you're not quite sure how much research she's done.
