This is a pretty good video on just that topic: https://www.youtube.com/watch?v=z-qi4OhCii4
You know, back in the pre-TLJ days I thought Reylo was idiotic but TLJ goes to great lengths to set it up. Finn, who I believed would end up with Rey by the end, is now with Rose and Poe’s got BB8.
While it might be a cliché, it is an interesting and a new place of the franchise to go. If they do it right, it could help Ep 9. But doing it right would be very hard to pull off, and they might see the entire saga fall apart if they fail. Something to keep in the back of our minds, I guess.
This is a great video that explains why, but I really don’t like the title of the video. I thought the best videos the showcase this were the three-part theory video series by the now defunct YouTuber, Vincent Vendetta.
I never saw Rey and Finn as a possible couple in The Force Awakens. I just saw them as friends. I didn’t hate that he ended up with Rose, though. I have faith that J.J. Abrams will wrap things nicely. I actually think that if the two survive in the end, with Ben being redeemed, it could help set up a possible fourth trilogy focused on their kids if Disney and Lucasfilm ever think about making another trilogy.
