A way to minimize subjectivity would be increasing the sample size. Most reviews are done by one person, and therefore very subjective.
However, if a rating service (not a review service) employed a team of 20+ readers, and each reader independently graded the work on a scale of 1-5, the average would be a better representation of differing likes and dislikes.
There would be no review. Simply a standard form for each reader to fill out at completion. Grades are compiled and averaged...done. Your book received a rating from "Such & Such Reader Group" of 3.8 stars....
