It seems this message board is filled with people that are biased against TKJ going as far as believing that the origin in it is highly questionable and not at all definitive.
What many fail to understand is that the Joker is unsure of his own origin, however TKJ is written by Alan Moore to give the audience his definitive origin of the Joker. Never has it been said anywhere that the origin of the Joker in TKJ is not definitive, in fact such an origin has been reinforced several times, only the Joker's awareness of such an origin is questionable, but everybody that has read TKJ is supposed to be aware that the origin there is true.
I only found out about Batman: The Killing Joke because everywhere I went online people lauded it as the definitive origin that cannot be questioned. By the way it is not my take on the origin, it is Alan Moore's take on the Joker origin. If anybody has a better one I would sure like to see you write it for DC, because the only origin we have is TKJ's origin.
So I am going to list different places that have fans of Batman: The Killing Joke.
Tim Burton claimed that The Killing Joke was a major influence on his film adaptation of Batman:
"I was never a giant comic book fan, but I've always loved the image of Batman and The Joker. The reason I've never been a comic book fan - and I think it started when I was a child - is because I could never tell which box I was supposed to read. I don't know if it was dyslexia or whatever, but that's why I loved The Killing Joke, because for the first time I could tell which one to read. It's my favorite. It's the first comic I've ever loved. And the success of those graphic novels made our ideas more acceptable."
Here are other quotes.
"It must be noted though, that it is in no way said that the background supplied is anything but the story told out of an observer's point of view."
"A story of the second Batman/Joker encounter later presented in issue #50 of Batman: Legends of the Dark Knight (Sept. 1993) corroborates the events of The Killing Joke as being true: when Batman faces the Joker for the first time, he recognises him as the Red Hood, whom he thought had drowned in the chemicals."
"Much of the Joker's story from The Killing Joke is also confirmed as being correct in 2004's "Pushback" (Batman: Gotham Knights #50-55; reprinted with #66 as Batman: Hush Returns, where the events are observed and reported by a third party — Edward Nigma, a.k.a. The Riddler — having no reason to lie. Nigma recounts that the Joker's wife was kidnapped and murdered by the criminals in order to force the engineer's compliance."
"Director Christopher Nolan has mentioned that The Killing Joke will serve as an influence for the version of the Joker that will appear in The Dark Knight film. Heath Ledger, who will appear in the film as the Joker, stated in an interview that he was given a copy of The Killing Joke as reference for the role."
If you do not like the Joker's origin in TKJ that is fine, but do not merely throw that origin to the wind for no reason, instead come up with your own origin that is better and then bring it out, otherwise if you cannot put out then just live with origin you have.
Because it doesn't profess to be the `one and only possible true Joker origin'.
You, Blue Jay, seam tot hink's its good because it tells the `definitive turth'
(Almost) everyone else (including some of those sites you lsited above by the way- I think you should read through some of those again) thinks its good because it goes out of its way to not tell anything of the Jokers originin in a difinitive way!
The beauty of it is that's its ambiguous, and the events that Joker mentions could be interpreted as actually happening, or could be mere delusions. That's why everyone else thinks its good (except for the one or two really recent stories, again as you and others have mentioned, that seam to miss the point and make the same mistake that you have).
Note: just because other people have made the same mistake as you, doesn't mean you ahven't made a mistake! Listen to Alan Moore, your god, and believe in what he has to say:
"If I have to have an origin, I'd prefer it to be multiple choice".
PS Didn't I say this thread was going to happen in my first reply?
