Some of the books are decent. However, most of them just rehash the same old Jedi vs. Sith storyline. Just having more than just two Sith as the villains would be uncreative because we already have that. Enough is enough. We need more focus on the Sun Guard or the Maladians. Why not a faction that hates all Force-users? Now that would be interesting. Also, even if the new trilogy were to prove that Vader's sacrifice was only meant to bring balance at that point in time, it still would cheapen his sacrifice. He kills Palpatine and... the Sith magically return like they always have because the writers can't take the time to think of any other villain. Why should the audience care if the villains don't die? If you want to see more Jedi vs. Sith bullshit, just play Star Wars: The Old Republic or wait till they decide to make a trilogy of movies a thousand years before the Rise of Darth Vader. Never mind the fact that most fans on the internet don't want the Sith as villains to begin with. Also the "light cannot exist without darkness" bullshit is philosophy, not a law. I don't know about you, but the Star Wars galaxy is too small. With billions of planets circling around a core, you'd think that there was more cultures, factions, races, and planets to explore. But unfortunately, a lot of EU authors seem intent on watering the universe down to simply Jedi vs. Sith. Furthermore, you're forgetting that some of the best books don't have the Sith in them(such as the Thrawn trilogy). And yes, having the Sith(same threat to the galaxy for the last couple thousand years now) involved is uncreative. As for the Jedi, they shouldn't go away completely because they show the spiritual side of Star Wars but I wouldn't have a trilogy all about them.
