I explained my biggest frustration about this new series on a Discord; the Sith Lord (Kylo Ren).
It's not the fault of the actor, it's just that the character is an incredibly lame idea for a Sith loving Lord.
KotORII has my favourite baddies. You've got the Scottish guy whose faced thousands of lethal blows yet stays alive through the power of sheer will and anger, the unstoppable force who consumes all in order to try and stop its unquenchable hunger which only builds as it continues to feast, and the great betrayer who played a Xanatos Gambit of epic proportions to murder her previous padawans and bring about the end of the Force completely.
And yet apparently the movie directors can only think of "Vader Wannabe with a serious Oedipus Complex".
And the idea of "Han's son is a Vader wannabe" isn't even anything new. J. J. somehow made it even less interesting than Darth "My parents are terrorist scum" Caedus.
At least they don't give Kylo Ren ridiculous force powers. I hope. We'll see if he starts using Force Time Travel.
