Not too shabby...
The Killing Joke isn't an amazing graphic novel, but it IS a must read for any Bat-Fan. Not only does it show one of the many possible origin story's for the Joker, but also the odd relationship that ties the Joker and Batman together-the fact that Batman may actually be the reason for The Clown Prince of Crime's existence.
Although many find it hard, this book could actually make you feel BAD for the Joker. Maybe.
The cooler colors on the deluxe edition aren't , in my opinion, doing the book any more justice. the more chaotic colors of the original help convey the madness inside the book. The deluxe edition does, however, look cleaner due to the new coloring, making it look more streamline. Overall: no matter which edition you get, you won't be dissapointed. unless you like dissapointment.
