To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Catalog of Unabashed Gratitude is superb and I highly, highly recommend that collection of his poetry over this. Bring the Shovel Down is actually a very interesting counterpoint to Catalog, as this is very negative, dark, threatening, vexed, whereas Catalog is quite optimistic, hopeful, and resilient.
