I love what this show has done / is doing. Despite some god awful cheeseball acting / dialogue throughout the series, this finale was, in my opinion, one of the greatest episodes in television history.........ever. And it ranks right up there with the some of the top moments in Star Wars. Fan service, you bet, but I'm fine with it. I get just as much satisfaction in watching the 100s of reaction videos on YouTube to this finale that I did when I watched it. Seeing the genuine emotion in those fans, both young AND old, should speak volumes to Disney.
And as far as I'm concerned, post-ROTJ Star Wars starts with The Mandalorian. And that's canon in my head. Those disappointing sequels are erased from my memory.
