You could argue that the original JKR work also portrays Dumbledore in a somewhat unflattering light. (He sent children after known dark wizards on multiple occasions, lied to Harry on several occasions, arguably stood by while Sirius was sentenced, etc.) As readers, we like Dumbledore, but he is hardly a paragon of virtue. I rather enjoy how MOR spins that.
