Authors, it's not the reader's job to help you write a quality product, nor should they have to explain to you why they gave a book how many star ratings without any reason.
Being obsessed with how someone reviews your work or how many reviews you receive, both good and bad will drive you crazy.
If you want to produce a "quality product" invest in:
A. Writing Class
B. Critique Partner/Group
C. Work with and editor.
