True that BatB is a major obstacle, to put it lightly. But still, if Frozen and Catching Fire could coexist... (and this doesn't have to do anywhere close to CF to be considered a success, though Liz Banks won't hurt provided future marketing builds her up).
Regarding the female characters, I've been seeing an active push recently to highlight Kimberly. She has her own spin-off comic which is apparently incredibly fun in the vein of Supergirl. And a lot of the social media activity for the trailer and posters has been coming from teen girls and young women. Too early to make a call on how it will land with those demographics, but Lionsgate could do with catering to them a bit more with further marketing. They also need to play up Ludi Lin.
