my only problem, and i kinda stated this in another thread, is if they bring back the "sith" it ruins Vaders who legacy. vader the chosen one to destroy the sith... only for them to return in 30 years :/ i dont know how i feel about that
bring in something new, like dark jedi... heck before the prequels we never knew the sith terminology and figured vader and the emperor were dark jedi's.
heres the chance to start something fresh, i just dont want vaders story to be worthless, devalues the who 6 movies to me..
on a lighter note, my friend and i were discussing this tonight, ive been preaching to him about the whole sith returning. and he told me, if kylo ren is a sith? why isnt there darth before his name? he must not be a sith....
