Example Input: I'm pretty happy with this.
Example Output: Good Review

Example Input: This would not fit through belt loops or any other fastening system. I had already placed an order that didn't fit. Not impressed.
Example Output: Bad review

Example Input: The book would be an OK value at twice the price. There might have been some really interesting research undertaken in trying to establish a list of the top 100 movies ever made and their critical success or failure, however, this kind of writing about movie review is very dry. It lacks focus throughout and could certainly use tighter editing. While I suppose if you are writing historical analysis, it makes sense, but for most readers, there were parts here that seemed so unfocused as they ran on.
Example Output:
Bad review
