Nightwing heads to Chicago to track down his parents' killer, ultimately landing in a muddled mess of a plotline that toys with a lot of great ideas but doesn't spend adequate time with any one of them. Almost as soon as he gets there he's drawn into a tangential storyline involving a crazed, murderous hacker who seems to basically be the epitome of Anonymous if it went fully bad.
This story completely does not work for me, though it starts off on a decent foot. We see at first that this villain, The Prankster, seems to be a man fighting back against corruption and societal injustice, only perhaps in ways that aren't as productive as he believes them to be. This is a potentially relevant, interesting commentary on the state of politics as they exist online, but it rapidly loses any of its narrative weight in favor of making The Prankster blatantly evil and despicable. Also, this dude hijacks all the TVs in Chicago (because of course he does) and tells everyone he's going to keep murdering their families until an allegedly corrupt politician gives their money back. Why ON EARTH would the populace be on his side? He is literally admitting to murdering people, while the politician only supposedly embezzled money. And yet, the people of Chicago are like "We love this guy who keeps killing us." It's unbelievable and insane.
Probably the biggest problem with the Prankster story is, by forcing Nightwing into this fairly random battle, we lose a lot of the personal stakes that come from him attempting to avenge his parents. The most interesting thing going on in this book is the revelation that Tony Zucco, a man Nightwing has been trying to track down for years, has turned over a new leaf, providing for a family he genuinely cares for. This is another potentially great storyline, raising questions of what is "justice" vs. simply "revenge," and whether or not Nightwing is even right to be so ruthless in his attempts to defeat Zucco. However, this gets derailed as well pretty fast, instead going in the most obvious routes possible and undermining every theme it sets up in favor of a "yeah I guess this guy's just bad" wrap-up.
There's also a third kind of C-plot going on in this book, involving the murder of Chicago's superheroes, which doesn't quite get rolling in this book (and seems to contradict itself here and there). I'm interested to see where it's going, but it doesn't look promising.
Oh, and this is example number 1000 of Dick Grayson showing up in the same non-Gotham city as Nightwing, but having no one put two and two together. To make matters worse, he's publicly searching for Tony Zucco both as Grayson and as Nightwing, but still not a soul seems to think he might be the same guy. He must be magic.
