Yes, this is my main problem with the episode and what it reveals about the showrunners' story priorities. I got the same cringey letdown I [Edited to remove future Star Wars reference] EVERYTHING IN THIS GALAXY NEEDS TO ALWAYS COME BACK TO EFFING SKYWALKERS!
Now at the end of this season's finale, we come back to the Skywalkers again. Uncanny Luke's reappearance not only reminded of the similarly unsuccessful CGI resurrections of Leia and Tarkin in Rogue One, but also reminded me of Star Trek Into Darkness "My name is ...KHAN!" No one in the story will think it's significant that it's LUKE; it's significant to them that it's a JEDI. The fact that it's Luke is cringey fan-service. YMMV, of course.
Still, I loved this season overall, and hope we get back to the edges of the galaxy for next season, but I fear more weaving back into the movie trilogies. Which means, mathematically, that everyone will eventually be a Skywalker.
