The casey/phillips run on Wildcats is some of my favorite superhero comics ever, and this volume captures most of my favorite moments of that run.
You can tell the team was looking to get experimental, and they definitely succeed. It's all about 'what comes after' the big conflict, which unfolded histrionically in the original run by Jim Lee et al, and was basically popped like a soap bubble by Alan Moore. Wildcats at this stage was a book without a high concept, or rather, a book about what happens when the high concept is just...gone.
It might sound boring, but it's really not. The lack of melodramatic conflict gives Casey a chance to dig into the psychology of these characters and create a mesh of intricate subplots that unfold and overlap and climax in wildly unpredictable fashion, which is really fun to read. It totally sidesteps the predictable rhythms of monthly superhero comics to great effect. You really don't know what's going to happen from one issue to the next, but if you can get into the characters, or already have some prior investment, it's really compelling stuff. Without the need to engage in huge bombastic gestures, you see carefully nuanced portraits of love, loyalty, heroism, and the search for meaning.
You get insights into these characters that are really fascinating, especially Cole Cash/Grifter, and 'Jack Marlowe'/Spartan. You see how Cole Cash is really a wreck of a human being whose only reason to keep going is love of an immortal warrior woman who basically has no use for him 99% of the time. He's a guy who has devoted his life to fighting and killing, and it has utterly drained and ruined him, but he nevertheless idealizes and adores this 'person' who embodies that life of fighting and killing in a form that can never age, get ugly and slow, or die. She is more like his object of worship than his girlfriend.
'Jack' has the most interesting arc to me, and something rarely seen in the treatment of android/robot superheroes. It's completely clear he is NOT human, and doesn't particularly need or want to be, but he still has recognizable emotions and drives, but in somewhat alien form. The best way to describe it is that he changes over the course of this run from robot soldier to a heroic machine, with an almost spiritual undertone to the way he thinks and acts. This volume contains the events that complete that transformation and set the stage for the 3.0 run, which is much different and not quite as enjoyable for many reasons, but this run is the goods.
Read a bit of what comes before to get the context if you need it, but this is great experimental character-driven superhero stuff, and very under-appreciated. Casey is a true writer's writer, and Phillips has long since been acknowledged as a master, mostly for his work with Ed Brubaker--you see here exactly why that is. In my view, you can't go wrong.
