It alternates a bit between three different ways you could approach making a Star Wars sequel:
- Nostalgia Trip: the same characters come back and do the same things but 30 years older.
- Mimic: new characters who are curiously similar to old ones, facing a curiously similar configuration of curiously similar enemies with a curiously similar threat, which they resolve with a curiously similar plan.
- New Story: new characters that occupy new roles in the familiar world, using them to explore new corners of it and create new situations and conflicts.
As you can probably tell from my phrasing, I like it best when its doing New Story stuff. A whole film of that would turn me full fanboy. As it is, the new stuff is still central enough that it kept me excited throughout.
