Adrianne Palicki held up her end of the log. She made a pretty respectable Wonder Woman.
At a stunning 5'-11" she certainly met the physical requirements for an Amazon princess. Lynda Carter was an equally Amazonian 5'-10". With Palicki's credibly tough attitude, she met the psychological requirements as well.
Had the story and dialogue been right, Palicki would have been as good a Wonder Woman as Lynda Carter.
No, the problem wasn't the casting. It wasn't with her. The problem was the writer/producer, the highly respected David Kelley.
Any superhero series has to have an origin story of some sort, however abbreviated. In this case, there was none. Nada, Zip. You just can't do that.
Sure, in media res. Get a running start. But you get a running start with the origin story. You don't skip it altogether. David Kelley, usually a great writer, really dropped the ball on this one.
A real shame.
