Aggregate ratings are mixed rather than uniformly positive, with five-star ratings making up half of the distribution and ratings across the other star levels as well. Without written feedback, the ratings do not explain what readers liked or disliked. For a collection of varied Java perspectives, prospective buyers should decide whether that format suits their needs rather than treating the aggregate as evidence about particular topics.
