3) Everyone Dies!
In retrospect, we should have seen this end coming. For one, Rogue One was all about new characters that were for some reason never seen or mentioned in the original trilogy. Director Gareth Edwards had also already confirmed that there would be no sequel and, most damning of all, Mon Mothma already told us in Return of the Jedi that many died when retrieving the Death Star plans (although it was stated to be Bothans). But still, when the entire crew of Rogue One bit the bullet in the thrilling final act of the film it came as a big shock.
It’s a move that makes this a much darker film that any other entry into the franchise. Yes, characters have died before in the line of duty and we know that their efforts go on to save the galaxy, but killing the entirety of the central cast of your movie is still a downer of an ending.
That being said, in this age of endless sequels, it was refreshing to have a film that so definitely sealed the fates of its characters and made for a complete story.
