CBS has released it's first extended trailer for Supergirl

CBS has just released a 6 minute trailer for it's upcoming series Supergirl and it's left me a little underwhelmed.

If only CW the guys behind Arrow and Flash had been able to do this.

I could be wrong though, what are your thoughts?

It's not a bird. It's not a plane. It's not a man. It's Supergirl. In the new drama from the world of DC Comics, Superman's cousin, Kara Zor-El, embraces her superhuman abilities and becomes the hero she was always meant to be. This Fall on CBS.
