I'm speaking in terms of Bane being the lone survivor when the Sith were completely wiped out, and his new order being a continuation of what was otherwise wiped out. I think the idea was that the Sith had been complete destroyed except for this one guy, who carried on with it in secret by means of the Rule of Two, and having other Sith sort of cheapens that.
That leads to into what I wanted to say to Lord Foley. Foley, I agree with you on the cheapening factor, I really do. There are so many directions that Star Wars
has taken recently that I saw coming a mile away, and wished it hadn't. However, having all of these little technicalities within its rich fictional history adds an element of realism for me that makes me appreciate it despite its cheapness. In real-life history, we're constantly discovering all of these little avenues that shed a different light on things we thought we knew. It happens with both ancient history as well as what was very recent (research Woodrow Wilson, Teddy Roosevelt and FDR, for example, and be blown away by just how inaccurate your previous perceptions of them were).
I'm sorry, but this argument doesn't even really address what I'm saying. You're saying these things are fine because of the in-universe explanation for them, and I'm saying they never should have been written because the in-universe explanations are contrived and retconny.
True, but you can't really say this of all of these instances. Some of these things, like Lumiya and Palpatine's resurrection, were written long before the prequels. How could these authors have known about things like the Rule of Two and the prophecy of the Chosen One before they even existed? Personally, I think it's admirable that Lucas Film has gone out of its way to come up with ways to work around it and keep these things canonical out of respect for both the writers and the stories themselves as classics. How often do you see that happen elsewhere? Not often.
As for what came after the movies, like Darth Caedus, Darth Krayt's One Sith, and various Sith splinter organizations: I agree with you wholeheartedly that they are cheap, stale, repetitive and predictable. (In fact, I once came up with an idea to bring the Sith back after the movies as well, and I knew that such an idea had all of these truths attached to it. But I had it set not so soon after the movie era and did my best to make it completely unlike anything we'd ever seen previously. But the Legacy
was announced, and it was such a movie-era wannabe that it was painful: a new Empire, the Dark Lord of the Sith is the Emperor of the galaxy, et cetera.) However, these things add realism to the universe. I get the whole Sith-are-gone poetic justice thing, but what's to stop some other group from rising up and declaring themselves Sith? What's to stop two Sith Lords under the Rule of Two from bending it beyond recognition by jumping through any loophole they possibly can? Things like this happen in real life all the time (well, not with Sith, but you know what I mean), and so it adds another level of veneration for the franchise for me. There are conflicting stories, inconsistencies, multiple accounts, and all that stuff. It sort of makes me feel like I'm reading a combination of Greek mythology, history and politics. It adds a whole new level of appeal despite being largely cheap in many ways.
