THE SITH

We need them. Because they're the main antagonists in all the SW movies...

Except for the OT. The real antagonist was the Empire. Vader was a fallen Jedi, but his role was still one of imperial servant. At the very end we find that the Emperor also has Force powers. But it wasn't set up or presented as "Sith" vs. Jedi/rebels. Accepting the PT (and the EU), I guess one might have to accept that most of the major conflict in the universe boils down to one of sith vs. jedi. I still think thats kinda lame :/

Certainly the dark side of the Force should continue to play a role in any Star Wars movie as using the powers of the Force for evil is a powerful part of the story. But I'd caution against making it so simplistic as "Attack of the 'Sith!'"

I don't think I'm splitting hairs about the OT villains being "Sith" yet the conflict not being based on their Sithiness. At least the OT shows a way of not making it be primarily about the "Sith" so as to make it more dynamic.

Some interesting ideas you have, so wanted to throw out my
