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.

This book started out fine but about midway through the story turned to a totally unbelievable scenario and I really don't care how it ends or what happens in it. There are just many other books on Kindle with much more interesting content. It does not have any depth at all. No real characters were developed enough for me to be interested if there was one. The writing is OK. You almost feel like you need an editor to read over sentence structure. So it's OK but no Great.
