Hollywood doesn't know how to write women characters. They either make them too strong or too weak. I'd would have liked this TV show if it was more focused on team work with Superman since they introduced him. But...NOOOOOOO... the writers introduce Superman and then throw him away like trash; we'll probably never see him again.
If Supergirl is to work alone, then why even introduce Superman? I'd rather have Supergirl reach Earth years before Superman and show her develop her powers gradually, becoming stronger each episode, and not make a super suit until she was strong enough to fly. This would make more sense, especially when the cape could be used for slowing her cruising speed!
Also the changing of characters race and sex really irritates me! Hollywood, if you must have a black character, create a unique one, rather than changing Jimmy Olson's race from white to black. And, if you must have a female villain, create a unique one, rather than changing General Zod's sex from male to female. Changing a character's race or sex has always irritated me since that Liberal hack writer Ronald D. Moore changed the original Battlestar Galactic's Starbuck character from male to female. Isn't Starbuck relating to a male deer? This just shows Mr. Moore's ignorance or disrespect for the art of writing.
