This felt like an attempt to break in on the success that Ed Brubaker has been having with dark, gritty crime stories in graphic form. It was successful, in terms of telling a dark, gritty story well, and with excellent art.
For me, the problem was the characters. I never liked or even sympathized with either of the two main ones.
For Mason, the father, I honestly found his decisions hard to believe, especially once they start circling the drain. Leaving his daughter in the car, in cold weather, while trying to talk his friend into leaving the bar? What? I'd have believed he would do something dumb, like bringing her into the bar, but as shown, what he did was way past reasonable. Then, there are the other crimes he commits over the course of the story. Sorry, but the cold nature of those means he's crossed the line too far to come back from.
For Becky, the mother...she's working a crummy job where the office has a habit of shorting the workers on their paychecks. She knows this, apparently. So, it happens again, and that's enough to trigger her going back to hard drugs? Sorry, but that didn't fly as an excuse.
The result is that both come across as jerks who deserve to lose their child, even if the dad was less violent and creepy. That means it's just a cold, grim story about crime where it was very difficult to care about the criminal. I can't give that more than three stars.
