See, when I read a post like yours it makes me re-think my own thoughts on it.
Thanks
Yeah, I know its a very short read. I myself love the longer arcs I can dive in for days or even weeks (thats one thing why I love Morrisons 5 year run so much!)
YO is kind of a subtle kind of story. I had to reread it once or twice to really get the full effect of it.
Thats just it! I love the fact that its also almost more of a James Gordon story. We don't have that many Gordon centric comics.
to redhood91's recommendation: I also really liked War Games, which is, again like City Of Crime, almost universally hated. Sure it is a bit heavy on the action side of things, which, in my eyes, makes it in some parts a bit of a drag to read, but all in all one of the coolest batbook crossovers.
I love the way Black Mask gets handled here and his confrontation with Joker in the War Crimes follow ups.
he has one of my favorite lines there, too.
He acquires a lot of Kryptonite and is asked what he's going to do with it and he replies with something like:"Heres what I'm not going to do with it: I won't build a giant mech suit, go to Metropolis and play King of the Mountain."

t:
Oooops, I just checked. That line's from Under The Red Hood, which started directly after War Games and before War Crimes. Still... really really like War Games.
Batman Black Glove and Batman RIP
follow up to Batman and Son by Morrison, in those two books the story really kicks of. Its dark, its philosophical, its deep, its crazy, stupid and fun, all at the same time. Cannot remember another Batman book I read with such a sense of danger and dread, which could've something to do with the "will he/won't he kill Batman"- thing. Morrison writes the Joker like no other writer and transforms the character into something even more terrifying than ever before! The Black Glove is a new enemy to be reckoned with, who has Batman in its grasp for longer than he would be willing to admit. The stakes are high, the masks are off and sanity is only an afterthought. I LOOOOOVE this run!
The follow up, Batman and Robin run was also great, but did not really grab me by the throat like these two books. To fully understand what happens to Batman after RIP you also need to read "Time and The Batman" and "Final Crisis", because everything ties together.
