I would like to be more familiar with the EU than I am, and am starting to take strides in that direction. I found that I appreciated TPM and AOTC a lot more when I read the novelizations for them, and they added enough to the story that I would think they could be considered EU, but I especially found TPM a much more fully realized story after I read Cloak of Deception. Sure, it's not a terribly action-packed story, but the political intrigue is important to understanding what happens to the Republic, so I felt it served a very vital purpose in the EU. So, yes, Klingon, the EU does add to my appreciation of the prequels.
We should start a few EU discussion threads (on different eras of the EU or characters or something). It would provide a nice distraction from all of the technical threads on bootlegs (which I'm thankful for, but have no hope of understanding).
