One of the greatest buildups here is watching the actors evolve. And with this narrative, “The Hunger Games” series proves itself to be much smarter than people give it credit for. This is an interesting challenge to “The One” narratives that make up most popular blockbusters, from “Star Wars” to “The Matrix.” Katniss, the supposed chosen one, is told that she was nothing more than “a face in the crowd.” But in a stellar twist, she proves us wrong. Here, Katniss is told not to fight and instead be the face of the revolution. Even though some bombs are going to be dropped, the key to winning Panem is symbolism. The “Hunger Games” movies are partially about revolutions fought through propaganda rather than violence. The biggest reason that “Mockingjay - Part 2” is such a satisfying conclusion is because it feels like every theme and every bit of character development from the previous films were actually building up to something.
