How can a film where most of the actions of the characters/villains in said film is to find Luke indicate that that’s not what the plot is about? That makes absolutely no sense.
Sorry I am not going to go through the same argument again.
And like I said that before wouldn’t that make the events in STAR WARS filler too by that same logic.
The main focus of the Star Wars is death star. You just cannot take it out of the film, like you easily could take out search for Luke from TFA.
