You just got through saying in another post that in the comics, Joker had no origin.
And you can't just ACCEPT a LITTLE change? The Joker had SO MANY differen't looks in the comics, so what look do you want? Jack's? Too bad, it's been done already. Now it's time for something different.
Your argument is ridiculous: "Not true to the souce material"...This Joker has the green hair, has the white face, has the red lips, HAS the scar that WAS portrayed before, and most, most most importantly: Has the psycopathic personality.
How is this not true to the source material? Because he looks like a lil different? Well, Jack's Joker had a perma-smile, had a godamn beer belly, and DIED in the movie; yet I don't see you complaining about that.
