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

Example Input: No real plot and it didn't get better as time went on, it read like a first draft when all those little things could have been fleshed out.
Example Output: Bad review

Example Input: It's hard to find a novel of this type and I was very disappointed. The prose is too good when compared against other authors who deal so much more with what it means to love someone. What does she love? He loves her. Can the truth ever be revealed? That depends on someone else. Who do we need to believe? This reader lost track of most of them.
Example Output:
Bad review
