A Brief history of Kevin J Anderson's career with Star Wars:
1994: The Jedi Academy trilogy. Here we're introduced to a bunch of retarded or whiny new Jedi Knights, and the Sun Crusher, the completely invincible superweapon more powerful than the Death Star and the size of a fighter. Also includes Admiral Daala, who is so retardedly incompetent that it's amazing that she hasn't been written out of continuity entirely, luckily she dies at the end. Also Han Solo goes skiing and Kevin J Anderson steals one of Timothy Zahn's Characters (Mara Jade) and makes her retarded.
1994-1998: The Tales of the Jedi comic book series, where we're treated to a frantic attempt to make the backstory of the Jedi Academy trilogy make some sort of sense, which didn't work so well.
1995: Darksaber. Kevin J. Anderson makes a Death Star shaped like a lightsaber. We're introduced to Durga the Hutt, who would have been Jabba the Hutt except he was dead, so KJA just came up with another name on the fly and wrote Jabba in anyways. Also Daala is back, turns out she didn't die, she just jumped away at the last second. KJA steals another of Zahn's characters again, Pellaeon and makes him retarded (Are we seeing a pattern yet?). Luke falls in love with a Jedi who's trapped in a computer and Crix Madine (the Chuck Norris Guy from Return of the Jedi) is killed off, because KJA hates Chuck Norris.
1995-1998: The entirety of the Young Jedi Knights series. Nuff said.
1996: A Boy and his Monster. A short story about how the Rancor and Handler used to be best buddies and how when the Handler was out walking the Rancor they were attacked by sandpeople and the Rancor saved his little buddy.
1996: Therefore I Am: The Tale of IG-88. In this we find out that the entirety of the second Death Star was actually under the control of IG-88 the entire time, and that the empire really had no control over it at all. Yes, that's right, IG-88, a bounty hunter who had a brief cameo in ESB, actually WAS the second death star. In this story he plants a virus and plots a huge droid uprising and just as he's about to launch his dastardly plan into action, Billy Dee Williams blows everything up while screaming "Yee-Haw!"
2001: Bane of the Sith. Well, I'll just let the picture do the talking:

After he was pretty much forcibly removed from the Star Wars writers circle for trying to ruin the franchise, he decided to ruin Dune instead.
But mostly we hate him because if not for him we wouldn't have to put up with this guy:

I'll close with some famous Kevin J. Anderson quotes:
I mean, I wasn't stupid. I knew we'd make money and sell a lot of Dune books.
I want to make it so that so many things happen... that you didn't expect would happen in this series, that you realize that you have to read every one of them.
The people who make policy decisions should damned well know what they are talking about before they make the decisions. There is nobody who is an expert on cloning who would be afraid after seeing Attack of the Clones.
We sat around on a hotel balcony with a bottle of wine and tried to figure out how you would go about blowing up a planet.
Because I've done these Dune books, and I'm a big outdoor hiker and mountain climber, I think that you can get along just fine with forests and things.
Each book will have a lot of cliffhangers, because I like that.
Star Wars has all the color, the humor, the action, the monsters and lots of aliens, so why not come up with an epic storyline that has all the politics, wheels within wheels stuff from Dune, but all the color and space battles and aliens from Star Wars, and just turn everything loose?And my favourite:
I'm playing amateur psychologist here, but these are very diehard fans and I think there's a little bit of jealousy here. I think they wish they had gotten picked to write Star Wars books.
