Hey...I've been a lurker for 3-4 years on and off but I registered to respond to your post.
Full disclosure: the creator of the show is my brother.
I would suggest that people watch the first episode rather than drawing conclusions based on the trailer.
There are some for instance who believe it gives bearded fellows a bad name. However, the heroine's father who adopted her and taught her martial arts is a bearded fellow (not shown in trailers).
There are some who suggest the burka costume in this context reinforces "suppression" of women. However, she uses this as a disguise but during her everyday life, she does not wear a burka.
Finally, referencing your post above, she does not derive her power from her costume, she simply uses it as a disguise.
In my opinion, I believe this will overall positively influence children.
