I’m not trying to prove you wrong. I’m merely stating that the Joker/Batman philosophy wasn’t always present in Joker/Batman stories. In fact it’s fairly new when comparatively speaking. And mostly it’s brought up by writers because of their long literary rivalry, something that couldn’t be written or even noted by fans until many years after their inceptions. So I don’t really think it’s fair to criticize Jacks Joker for lacking that so-called philosophy, really first brought aloud in Killing Joke, which did influence Batman 1989, but was also extremely new at the time too. So Jack’s not inaccurate, just accurate to a different depiction of the Batman/Joker duel. Plus it could be argued that it is there, just not as blatantly. Nolan is often criticized as being pretentious, which I can def. see how some could view it that way. Instead of having the audience themselves find the Jokers mantra, the Joker instead speaks it very aloud in The Dark Knight by describing his every "chaotic" reason.
Yeah, I mean, you don't expect the Joker to waffle on about the ying/yang of their struggle etc every time he appeared , it would get tiresome. But, you do get refences to this frame of mind he has on the situation through the books of the 70s and 80s every now and again, it was a staple that the Joker's character was partially composed of this attitude in regard to his struggles with BM.
'5 way' was a milestone, and what every succesive Joker writer would have based their character off. Denny O Neil was editing the books, and would have kept that philosophy in(that he introduced), as in, he would have rejevted anything that deviated from it. ie The Joker may hate BM, but he respects him.
I have to say, it was there in the books(edit: post '5 way'), refs to their ongoing titanic battle of wits, and how they were made for each other.
I realise Jack's could be said to be based on the earlier era, but you were saying most Batman comicbook fans you came across preffered Nicolson, when this is simply not the case. To a lot of fans, myself included, we finally got the Joker you would expect to see in a modern BM tale, ie since '5 way'.
edit: and you have now edited in since I quoted you, that you have come across many cb fans who prefer Ledger, but that was different to what you were saying before, which is what I was talking about here.
The Joker explaining himself and his actions lead to some great dialoge, and that fantastic interogation scene, which was not the usual interogation room scenario, I wouldn't change any of that personally.
edit: What the Killing Joke did was bring this situation to a head, but it had always been there since the modern joker was introduced in '5 way'.
I've said this in a KJ thread before, and i remember this feeling when I first read it, but the best thing about the KJ, to me, as a long term fan, was that it contained the no bs conversation between BM and the Joker we had all been waiting on.
With the refs to their ongoing battle of wits, made for each other etc, Alan Moore took that on board and had BM confront the situation with his 'We're going to kill each other' spiel, the conversation that ends up getting aired between them at the end of the book(and could not have been executed better imo).
edit: RE: your statement that the ideological rivalry is there in Batman89, but just not as blatant.
No, it's not there, what is there is a hamfisted attempt to give the Joker and Batman a connection through making the Joker the killer of Batman's parents.
What this results in is giving the audience the impression that Batman is all the more determined to hunt down and kill the Joker beacause of this action, not because his crimes are growing more out of control, and it becomes an act of revenge, not justice.
Why not just have Batman going after the Joker because they are natural enemies, Batman, the guy who tries to control the chaos of the world, and the Joker, the bringer of chaos.
They went for a usual 'Death Wish'/'Commando' revenge movie trope, instead of writing up a more serious and intelligent Joker, and in the process gave Batman a quality he had never had before in the comics, that of a bloodthirsty killer dead set on revenge.
