It's okay, though I probably wouldn't kick off a new Wonder Woman series in Gotham (or Metropolis, or Central City, or Coast City, etc.). Not great, not horrible. Kind of interesting, but there's definitely a limit on how interesting Batman's villains are against the big dog DC heroes. Usually, you need some plot contrivance to make that interesting and plausible.
Anyway, thinking of this and DC Universe Online (WW's mentee's start in Metropolis), WW needs a home city besides Themyscira, and probably not a real world city that will be replaced by another real world city as her home base in the next continuity.
EDIT: Looking back, though, you have to go about halfway through the book before WW finally appears. Two WW titles come out this Wednesday, and she only appears in half of each title. Oh well, I guess that adds up to one whole book...
