It's really hard to build a story around an intentionally unlikeable character and keep it a compelling read. And in Manhunter, Andreyko nailed it.
The lead and title character is Kate Spencer. A top prosecutor, she reacts to losing yet another supervillain case by stealing high tech goodies from evidence lockers and turning vigilante herself. Kate is no selfless wonder herself. Her vigilante turn seems to be inspired as much by an inability to accept defeat as by any thoughts of justice. Her personality is abrasive, and she's a terrible mother. And still a compelling character.
It's because Andreyko's writing is so solid, and because Kate's failings are realistic and not too far over the top. And I loved the way Andreyko integrated the rest of the DCU. The Justice League's appearance was spot on. I'm very much looking forward to continuing this series.
