I’ll once again grab my comments from another post, this time one from the Dick Grayson Fan Club:
To elaborate, I find all of the “cutting off and reattaching Joker’s face” stuff from the New 52 to be utterly inane, and I remember being really ticked off when it appeared that the Joker had done the same to the Bat-Family, but the ending of the story was fairly satisfying. I generally like Snyder’s work with the Joker (and Red Hood One) more than I like his non-Joker stories.
