I binged it over the holiday weekend and enjoyed it. I hadn't read (or even heard of) the books, so I can't comment on any changes made. I might pick them up later based on people's rec.

As far as the show goes, it had a few slow moments, but overall I enjoyed how focused and uncompromising the revenge plot went. I thought Pratt did well given the subject matter isn't his typical quirky, fun roles.
