What I think hurt the show
A couple of things come to mind. It was not a good title for the show and the stories were limited about only women criminals. They should have had story lines about all types criminals, men and women baddies, and could have done so much more with the show.
That being said, I thought Tricia Helfer and the rest of the cast did a pretty good acting job.
This is not the first show in which an actress played a Texas Ranger. Nia Peoples played one in Walker, Texas Ranger several years ago.
