I think you really have no idea what Dark Jedi are. They're a faction of Jedi that believe in using the Dark Side to reach their ends. They form their own council and their own order. I think it's a very fair comparison. The Sith and the Jedi are two opposing "religions" (if you will), while Dark Jedi are a branch from the Jedi. I think if you had a better understanding of what the Dark Jedi were, you'd understand that the films could be done in a very deep manner, exploring concepts not yet explored by the first two trilogies. And the Mandalorians are in the CW and that's not EU. CW is canon - and they are awesome in it.
The Clone Wars still aren't the films, and they shouldn't build on TV references. Pre Vizsula's cool and the Mandalorians are a good, but I mean they're not the only cool entity in Star Wars. We already got an army of Boba Fetts in the prequels I don't think we need another one.
Anyway you bring up the Clone Wars which I think demonstrates pretty well what I mean by Dark Jedi being a bit of a step down from the Sith. Notice how much more menacing say Darth Maul is than Savage Oppress and Assaj Ventress. Even in the rest of the EU, the Dark Jedi I am familiar with are like Xanatos, Sora Bulq, Dessan, Garrek, etc.
They're always decent villains but they're never able to live up to the villains from the films. The way I interpret Anakin bringing balance to the force is that Anakin simply leveled the field. It's kind of biblical, Anakin purified the flawed Jedi order (who even in the original trilogy encouraged Luke to kill Vader) by wiping them out, then by doing the same force the Sith Lords by killing himself and the Emperor. He didn't destroy the Sith he destroyed everything.
My idea is that the galaxy is a bit of a no mans land, the Empire is trying to regroup, the Rebellion is trying to reform the Republic, and Crime Lords have taken claim of neutral space. Luke has tried to rebuild the order but it has failed because he is trying to literally rebuild it rather than reinvent it. One of Lukes old Students has been working to discover old secrets of the Sith (maybe Darth Plagueis) and wants to reestablish the Empire.
A new group of characters comes. Most of them end up with Leia, Han, and Chewie trying to fix the Republic, but one of them finds Luke and ends up helping him accept that it is not his destiny to rebuild the order and he must pass the mantle. Maybe the kids a bad seed and works for the crime families and has learns of the dangers of the Dark Side from Anakins ghost, and gets council from the spirit of Luke becoming the Obi-Wan type figure.
Did you even end up reading the SECOND storyline I had in mind? The one with the invaders?
I did and I see where you're coming from, but I just don't see the personal conflict with the Yuuzan Vong. Like in the bigger picture of the Rise of the Empire there was Obi-Wan losing his student and friend, in the bigger picture of the Rebllions struggle there was Luke and his father, I don't see how that could work. Not to mention Star Wars is usually more praised the closer it is to a more timeless story (good evil, wizards, knights) that doesn't need to all the sci-fi space elements. It's one of the major things that separates Star Wars from Star Trek, it's a fantasy with Sci-Fi elements, not Sci-Fi with fantasy elements.
And that's personally why I really want them. I feel it humanises the characters. But I can understand your point.
I see what you're saying and I partially agree. Seeing say Ewan go to Alec or young to old Harrison Ford is okay, but imagine we see Luke looking like Mark Hamil today. It wouldn't be like "Oh Luke the years haven't been kind" it'd be like "Oh Luke...you really gotta hit the gym man". I mentioned "Jedi Master Physique" on another thread, and I think the best analogy for seeing Hamil as Luke today would be seeing an obese Police Officer thats just gotten lazy and sat around eating donuts. Besides with all of the people making fun of Yoda bouncing around, imagine how many people will be making fun of tubby Luke doing flips and what not. He needs a trainer, a diet, or a new actor.
