Why does every one hate the Supergirl Trailer so much?

I don't get it people are mad she is girly when she always has been.

She is NOT Wonder Woman, Black Canary, Hawkgirl, Raven, Black Widow, Emma Frost, Ms. Marvel, who are much darker heroes & less girly in there personality.

Comics / graphic novels : Kara Zoe El cause there is another Supergirl that is NOT Kara.

Sliver age - she is bubbley in of those comic, witch were aimed at girls obviously.

Modern age pre New 52 -

Superman / Batman : Supergirl

She is darker cause she arrived on earth has a 16 year old instead of 12 like sliver age. But this book is pretty good. It's aimed more at guys than girls.

Supergirl power - darker Supergirl aimed at guys. But the book is Meh.

Supergirl : Candor - very dark Supergirl - this book just sucked. It's story is utter garbage.

Supergirl & the legion of Superheroes in all 4 graphic novels Kara is bubbley & badass both. These are really good.

Supergirl : Way of the World - a decent read even if it's girly & DC try's to leave her bubbley. Since they tried to switch Kara to be a more girl friendly book

She pretty much stays in the trying to be bubbly but not really until the new 52. Where she is clearly not bubbley.

So what's wrong with the Supergirl trailer?

If they do live action sailor moon is everyone going to be upset sailor moon is a cry baby?
