Vice Admiral
Well, the trailer looks ok (although I'm starting to wonder if there's some unwritten new rule banning Star Wars leads from being male), but....
I'd say that IF the lead characters are, or are based on the characters from dark forces, they are doing a good job, since they would be bringing in the story from the point of view from Jan Ors(I have yet to see a confirmation of the real spelling of her name, but I'm prette sure "Jyne Ersoa" would be to lame of a pun), which gives it a nice edge, more then one of us played as Kyle Katarn, where Jan was the damsel in distress and more then once your savior, viewing it from her point of view would be fresh. Seeing someone bringing Kyle to the big screen, would be awesome. A warsie friend of mine also said the military man in white is likely Thrawn. They did get the marketing done, since the internet is now buzzing over things regarding the movie. And the Expanded Universe does need a proper sendoff.
And as for the female lead roles, they can overexaggerate, but a female lead (in stereotype) makes the movie more accessible for girls. It also happens in other sci-fi, to the point where somebody shouts "female lead!!" and people tend to follow(Dr. Who is one of the worst communities, since the possibility exists of genderswapping and has been confirmed more then once, a few brave fanatics are pretty much demanding a female doctor, mostly pointing to theirselves as to why it should happen, comment on them and the reply will be "transphobic bigotry"). People also want a female James Bond, and a female Indiana Jones now(I never heard anyone ask for a male Lara Croft though...)
