I actually dug the issue and didn't find much fault in it. I thought the length was perfectly fine for the particular story they were trying to tell. They can easily go into further development on other aspects of Cheetah down the road. Oh and the FBI agent is the New 52 introduction of Manhunter (Shaw). He isn't really a big player so I wasn't expecting too much from him here.
@undeadpool: I rather read Azzarello's take. I'm not a fan of the Villain event thing. I liked how the Wonder Woman comic wasn't connected to the rest of the New 52 titles.
Azzarello doesn't care much for WW's rogue's gallery or general cast. Its why he used practically none of them in his run. You can read Azzarello's writing with First Born next week.
