The theory was that at the end of the trilogy, Ben would be redeemed as a Jedi, and Rey would fall to the Dark Side.
One complete trilogy to tell that, it would be seriously lacking interest… which is sadly the case of the new trilogy so far 😕 i’m not hyped by the new trailer: repurposed ideas, Mad Max 3 vibe, and many shots which look cheap (the darth Rey shot is terrible, looks fake with a catchy weapon, it’s ridiculous).
