Probably, but 2 of the 3 movies are over so if the Knights of Ren are going to appear they better get on with it. It's a little odd to hear about them and never see them. Just like being told how powerful and important Snoke is, only to barely see him in the first movie and then he immediately gets gaffed in the second.
Rian Johnson scrapped most of what they had set up in The Force Awakens and made a completely different movie. His new definition of a Trilogy is 3 separate movies that have almost nothing to do with each other. It's just bad writing if you ask me. You never get time to care about the characters.
Sloppy story telling.
LOL yes, Force Awakens did a great build up of many things and added a lot of things they could have worked with and developed further in the trilogy, which all melted down thanks to Rian Johnson.
Knights of Ren, Snoke, Phasma, Rey's origin, the upcoming Luke and Rey's trainingmontage a la Empire (great cliffhander in Force Awakens) etc etc
All went to shit
Instead he added a Casino-scene clanking down on the rich and fortunate, put down even more white males (Poe getting shit on) and promoted even more Feminism (female leaders like Hondo etc) as well as promoting even more diversity and interracial relationships with fat rose and neegul.
The female character i liked (Phasma) even got shit on.
"Phasma will definitely get more scenes and action in The Last Jedi". lol
That Liberal Cuck sure ain't no Arrogant Brit Douchebag!
