Totally good, but you probably read it 20 years ago and have known that all along. It's interesting to note that I'm looking forward to the movie less, having read this. The scene with all the conversation leading up to the big reveal is not going to play well on screen.
The pirate storyline felt a little plunked to me, but whatevs.
This writer makes it look so easy. How come more graphic novels aren't grappling with weighty, existential issues like this? I mean is Batman a Byronic Hero or not, come on.
