Finn’s ideal character arc of dying against the regime was interrupted by Rose’s stupid sacrifice that, if Mary Sue had not come to the rescue, would have killed all of her friends.
Finn and Rose will have a baby together. That’s another common jump the shark moment. While I am thinking about it, the can have a “very special episode” scene with a very special guest star, have Poe jump over a Tattoine Land Shark, and bring back Jar Jar, this time played by Ted McGinley. If you are going to jump the shark, jump the shark!
