I must admit, the title intrigues me.
I don’t want to speculate too much, but the title suggests an ending on a high note.
A Rise is something coming into being, gaining in power and prominence. This is distinct from a Return, something gone coming back, or a Revenge, the destruction of a foe. A Rise can include these things, but does not have to.
Skywalker has been, heretofore, a name. A surname. Three characters in Star Wars have had that surname: Shmi, Anakin, and Luke. Leia had the right to it, but never used it, retaining the Organa she grew up with. Kylo Ren was born with the surname Solo.
But this title doesn’t feel like a surname. It feels like something else. It feels like a mantle. An order, perhaps.
Who knows. Maybe it means nothing at all. “The Force Awakens” has no particular meaning to the plot of that film. However “The Last Jedi” did.
We shall see.
