Oddly glib and disappointing. The gravity of genetic manipulation and its dark history is fascinating, if grim, and Rutherford is extremely well-researched and capable of sharing that story. What I took issue with was his tone throughout, which was maybe a little on the cheeky and "isn't this crazy" side, which completely undermines the book's more complex and admittedly undigestible depiction of the evils of eugenics and how they impacted (and continue to impact) humanity as a whole. Shrug.
