My first reaction to this yesterday was... very negative.
The swinging camerawork in that desert scene is super questionable, right?
If Palpatine has been pulling the strings this whole time, I will be extremely disappointed. Some argue that his presence could end up being an effective bookend for the whole saga, but I am supremely skeptical.
If Rey turns out to be just another hero in the Skywalker bloodline, I will be CRUSHED. The random serendipity of her ascent is literally the best thing about this trilogy. I don't think I could forgive JJ. That said, I am less and less worried that this will happen. Such a reveal would probably not be in the title of the film.
And without having seen the movie, it's an extremely bad title. We can only guess how the actual content transforms its meaning, but... I am also skeptical on this.
There are some reasons for hope. I'm very excited for more Rey content, and it's coming from the guy who created this character, rather than Colin freaking Trevorrow, which, yikes, who knows how that could have gone. This is going to be empowered Rey, too, presumably with echoes of empowered Luke in RoJ, which yielded some of the best scenes of that trilogy.
