The stars were aligned against this project from the second it started to be released. We all understand you worked on the show JML so you got to be closer to the project than others but as an outsider looking in, from what was being said about it to the leaked scripts (yes they weren't final), to the test audience reactions something wasn't working. Smallville is still considered by many as not a Superman show because it changed so much but the reason it endured is watching that pilot it felt like a Superman story, it felt epic and despite the bumps and bruises held that mystic, that hope that he would turn into Superman.
This show seemed to have none of that. We wouldn't be watching Diana becoming Wonder Woman, she already was. We would be watching a hero in action and it obviously didn't work. I'm glad the show didn't get picked up just like I was glad with The Flash "Quantum Leap" concept show was shelved because that would have sucked too. You could do a Wonder Woman show steeped in the mythology, slammed with the hero's journey or even the learning about the character itself and it would have done spectacular, themed shows like Camelot, The Borgias, Spartacus all have shown it will not only work but provides the escapism that people long for, this obviously didn't especially considering that Kelley's strong suit is tongue in cheek humor based in an urban setting which this felt like.
Networks shying away from this material isn't for the worst, they are more apt to cancel at the first sign of danger anyway. If it were up to me we'd see Comic Book shows on premium networks or at least cable networks like AMC who will be more willing to put more into a show whereas networks we are just talking about a timeslot.
