This was my favorite issue in King's run yet and has really sold me on him on Batman. You get a fresh interesting take on Batman's psychology here (and I like those whether it's my ideal or not, I love Blind Justice and it has a very negative view on Batman). The issue is very introspective about Batman and what makes him tick in King's view. This chapter cements what "I Am Suicide" is trying to say about Batman so far.
And Janin is off the charts experimental here and awesome.
