The marginalization of Finn was one of the most disappointing things for me among a host of disappointing things about the Star Wars sequel trilogy. It almost seems like Rian Johnson’s main mission with The Last Jedi was to marginalize all the diverse characters (Finn, Rose, Ackbar) in to useless side quests or off screen deaths and just add more white leads like Holdo. I wonder what the movies could have been if Rian Johnson hadn’t gotten his racist fingers on it.
I’d love to someday see Finn show up in a Star Wars Prime show and ignore the last movies completely. Sadly it seems the more things get better, the more they stay the same. Finn and Rose deserved better.
