Is Luke Rey’s father?
Does Rey turn to the dark side?
Does Rey turn to the dark side?
Because this is a remake of the Empire Strikes Back and the Return of the Jedi, you have every reason to expect that those questions would be important. The reveal that Vader was Luke's father was one of the great twists in Hollywood.
This movie leads you to the point where you think "now I know where we are going," then veers off in a completely different direction. Which is original and irritating at the same time. If they wanted to go in a different direction, why lead me right up to the edge and then turn around? Just start in a different direction and keep going.
