I disagree. If anything I believe it added a layer to the mythos and to the Batman/Joker dichotomy. Fans always like to tout that the two are bound together by the cosmos. Hell, even Nolan hinted as much at the end of The Dark Knight.
Is it unfaithful to the source material? Yea, sure. But it doesn't tarnish the relationship between the two of them in any way. Remember, Burton was presented with the unbearable task of telling the story of Batman over the course of just a single film. He had to condense all of that mythology and all that history into one movie. By making Joker the murderer of Bruce's parents, it suggests that these two were always destined to cross paths. That one simply could not have existed without the other's help.
