I really thought this was supposed to be some earth shattered storyline, and in the end, Joker appeared to do *nothing*. He even went so far as to PRETEND to cut their faces off, so what was his motive? He wanted Batman to let them "die"?
And the end was so odd, what was the isotope all about, and why did they all refuse to go see him? So weird. I thought this was supposed to be some earth shattering event where everybody died, and the line was changed forever. I wouldn't go so far to say I am disappointed, but I guess it was overhyped to me.
I liked the strong "Killing Joke" and "Arkham Aslyum" vibes it had.
