This is an interesting observation and would’ve made a fitting theme for the film (and the trilogy): Rey and Ben Solo’s situations are reversed from when we meet them; she finds a family and he ends up alone.
Lots of great stuff here, I like your point about the characters names being especially significant to this trilogy: Ben chooses a name for himself while Rey is missing one.
I especially like your ‘Indiana Jones’ ending. To me, that’s the central issue with Abram’s film. You can tell he struggled with the ending, and it doesn’t really work. He brought back Palpatine as he felt he needed a villain to replace Snoke, but I like the way you manage to make it work just with Ben. Nice job.
