THIS IS WORTH MENTIONING

When using the Amazon app, after I click on the book and scroll down there's a section that says "Top Reviews". Most of them are 5 star. I clicked on the first one and it said "one person found this helpful"

When I click on all reviews, there are many of one star reviews, some of them with THOUSANDS of helpful votes.

Every time I reload the page the top reviews are different, not sure what kind of algorithm Amazon is using here.

ALSO: If you write a review, make sure you review the hard copy and paperback versions, since they're listed as different products and do not share the same reviews.
