I get the feeling they'll try to have it as a trilogy, focusing on the ascension and moves that Snow makes to become the President of Panem. And if they do, and this film starts a series of more political action/dramas set in the Capitol and other districts, I'd be completely on-board for this.
I very much enjoyed all of the films, and even read the books; and if they are going more darker with the tone on this, and with the focus more on expanding the lore and backstory of the Capitol, then there can be a lot of potential.
