There were a few other characters brought back in "Rogue One". C-3PO, R2-D2, Mon Mothma, Bail Organa, Governor Tarkin, Ponda Baba Colonel Evazan, and Princess Leia also made appearances in the movie. Nevertheless, like Vader, they failed to bring that sense of nostalgia back the same way that "The Force Awakens" did.
It is possible that this lack of nostalgia in "Rogue One" is because we were treated with so much of it just one year ago. Fair. Even so, "Rogue One" was simply lacking that push that made it a memorable addition to the saga.
Until the end.
Darth Vader's final scene in "Rouge One" was absolutely terrifying.
Ironically, the beginning of the greatness of "Rogue One" didn't really come until after the main protagonists died. Nothing against Felicity Jones and Diego Luna, who did a fantastic job portraying their characters, but the moment when the movie's stereotypical plot took a twist was when Darth Vader's blazing red lightsaber illuminated a hallway filled with rebel soldiers.
I've seen all of the Star Wars movies countless times. I understood that Darth Vader was powerful. I understood that he was ruthless. I understood that he was willing to do (or kill) whatever he needed to get what he wanted. But I never thought of him as a scary character.
The ending of "Rogue One" changed that.
Watching Vader absolutely slaughter the helpless rebel soldiers with such a calm demeanor completely changed the way I viewed the villain. It was easily one of the greatest scenes in Star Wars history.
The movie then proceeded to shock anyone who wasn't already astonished by that scene.
Princess Leia's appearance in "Rogue One" was brief, but it was incredibly powerful.
"Rogue One"'s ending wrapped up the movie's plot very well while also directly connecting to the fourth episode of the saga, "A New Hope". By using CGI and actress Ingvild Deila to recreate Princess Leia Organa , director Gareth Edwards was able to perfectly link the ending of his movie to the original Star Wars movie.
Leia's cameo was the best-kept secret of the film, and absolutely no one saw it coming. The purpose of "Rogue One" finally became clear. Without the events that occurred in the movie, "A New Hope" wouldn't have happened.
Emma Yorkes '18 agreed, saying, "I really enjoyed the ending. It tied this specific Star Wars story with the other ones and I thought that was really interesting."
