Query: Darth Vader still #1!

No way in the world can I believe that Xixor is as smart and cunning as Darth or Jabba. There was not enough space action or blaster showdowns as it should have. Dash Rander was okay... Xixor and Guri just plain sucked. Mr. Perry took way to many chances throughout the book to build them up for nothing. I hope they both died and never come back. As far as Darth Vader's equal, PLEASE. Not on even. Vader has been around for decades, and all of a sudden I'm supposed to think Xixor is just as ruthless? Nope. I was tricked by the bestseller thing at the top of the book. No more.
