First impressions are a powerful thing. They blew the "big reveal".
That 'Jim Lee'-ish costume was the wrong thing for the studio to put out there as a first look. This newer costume would have a better choice. This looks like something she would wear in a fight. It also looks like it could be believable on screen.
Neither shot is dynamic in any way. Couldn't they have chosen something from an action scene?
There is no right or wrong thing for the studio, I honestly believe they would have been crucified no matter what they released first.
I can tell you this, the main reason they put this photo out was so the Paparazzi swarming the set wouldn't get a shot out first. She hasn't been in a fight on screen yet, that's next week.
