A feature module that uses entity reference to produce a fully capable product review function. A content type is created called ?Reviews? and (on the configuration page) you can select various nodes to attach reviews. Each review has a fivestar field (with the option to add additional fivestar fields to help rate products, shipping, and other categories). Blocks powered by Views come out of the box that help summarize the customer feedback per product. A Catalog view comes out of the box which shows you how to sort products based on rating and can provide a platform to build your own ratings-based catalog page.
