Interesting to see how they made up this new character which of course has a Batman vibe to it but is in fact so different. Yes it more or less starts out as a revenge driven thing but quickly turns into much more. So many topics are touched in here:abuse, "excess is access", addiction, dark sides of celebrity culture, mental health and more.

The artwork: it's interesting to see that half way through the book they brought in a new artist and separate colorist.
While the first artist, Tommy Lee Edwards, has a more gritty and rough style, the second artist team, Shawn Crystal and Jean-François beaulieu are more clean and a lean towards the style of the Batman animated series. Edwards is awesome doing backgrounds, always showing a great level of detail. But in terms of characters he fails to make them distinguishable. For example the heroine and one of the antagonists look almost the same and that's not on purpose.
Crystal and beaulieu are far better in that regard giving each character distinctive features. However, in terms of surroundings and backgrounds they are quite flat and boring. So we have a bit of a conundrum there...

Oh and there's a great afterword by Gerard Way in this, too! And a small bonus comic!
