I saw Episode I: The Phantom Menace when it came out, so I "get" the universe, but I didn't go to see any of the other movies and now my girlfriend wants to see Episode IX: The Rise of Skywalker. Is it going to make sense to me?
I know there will be some new characters and plot points and so on that carry on from the parts in between, but I don't know how serialized the movies are and whether it's just going to be completely incomprehensible without all that context. That is, I'm worried that it's going to be two hours of total gibberish - I understand that there will be payoffs to plot threads that aren't significant to me.
I figure movies are meant to be accessible to someone who walks in off the street. However, I saw there was a "Do I need to have seen The Last Jedi?" question on this site where the answer seems to be (1) yes and (2) incomprehensible, and that's gotten me worried a bit.
By sheer cultural osmosis I am aware of the big twist from the old series that
Luke Skywalker's father,
so presumably they're related to Anakin Skywalker in some way and so is this film, and I know that
Leia was played by Carrie Fisher, which created some problems for the new movie. I also saw some of the TV movie with Chewbacca taking his human friend on a spaceship to visit his planet, with the song and dance scenes, but I understand that's a sort of elseworlds project outside the canon of the series (I don't remember much of the part from the Chewbacca planet anyway). I did ride Star Tours at Disneyworld once and it was all fine without the movies. That's the limit of my Star Wars knowledge so far.
I guess on this site people will tell me that I should've seen all the movies, and maybe I should have, but it's not going to happen before this screening. So it's probably better if I've seen everything in between, but is it a complete lost cause otherwise? Is there something I particularly need to know about for it to work out?
