Probably thanks to the new movie trailer, the classic graphic novel The Watchmen is now #2 on Amazon. It's well-deserved. I can't say enough good things about this book - I've read it at least ten times. But for skeptical EconLog readers, this one should be enough: The Watchmen is the Best... Utilitarian Parable... Ever.
HT: Steve Blatt, who gave me The Watchmen as a birthday present back in 1992 or so.
