You know what makes Rogue One so incredibly genius? The simplicity. It seems like a fault at the beginning, something just doesn’t feel right: the characters don’t seem like protagonists, the story doesn’t seem that important, everything feels like a side story that no one ever knew… and then you realize that that’s exactly what it is, its not supposed to be a big flashy story with your typical heroes, its a story about a bunch of nobodies who did a very small part of the rebellion, but without them nothing would’ve happened.
Nobody gave them recognition, nobody even cared, but they saved countless lives and died with no fame or recognition. Just like it happens in real life.
