I know, I know, another Batman story. What can I say? They're good reads. The Killing Joke was no exception. It was written by Alan Moore, and drawn/coloured by Brian Bolland. This was the deluxe edition, reprinted 20 years after it was originally made. My copy has the following quote by tim Burton: "I loved THE KILLING JOKE...It's my favourite. It's the first comic I've ever loved." While I don't exactly agree with this (My love goes to Knightfall part 1), The Killing Joke was pretty amazing.
When I bought this, I didn't bother reading the back of it. I just assumed it was the story of when the Joker killed Robin. While I was very wrong (Robin does not appear in this story at all) it was still a very interesting and involved story. The Joker believes that one bad day is all that separates so called normal people from the psychopaths of Gotham. To prove his point, he's decided to subject Commissioner Gordon to the worst day of his life.
This story is rather brutal at some points. To give Gordon a bad day, the Joker does some extremely terrible things both to Gordon and his daughter, Barbara. But The Killing Joke is extremely well written, and the art is fantastic.
Oh, and here's a bit of trivia: the original edition was not coloured by Brian Bolland. He recoloured everything for this deluxe edition. He also changed some of the drawings. So if you have both this copy and the original (which I don't, I just have the deluxe edition) then you can go through the books page by page looking for the differences.
The Killing Joke is a must-read for all of the Joker fans out there!
