Lucasfilm recently announced that it would not be considering the Expanded Universe stories found in the novels/comics/games when building the new trilogy of films.
My reaction to this is: Good. I read almost all of the books released through the mid 2000's, and aside from the fact that they're almost all bad to fun but mediocre, they took the universe in a direction that doesn't really reconcile well with what's in the films. Adhering to the stories within them would be a futile effort.
big problem I have with expanded universe stuff is that it gives every
background character an extensive history and makes everyone that should
be minor have great universal importance. Not all of the books/comics
do this, of course, but the ones that do really bother me. I think it's
incredibly stupid that a random background robot in the bounty hunters
scene in Empire becomes the brain of the Death Star II for some reason.
over explaining every little thing, the books kill a lot of the mystery
and the fantasy of the films. It's a series about family and faith with
an expanded universe obsessed with cataloging and categorizing every
aspect of it. The authors of these books do what Qui Gon did in Phantom
Menace; instead of placing his faith in the kindness of young Anakin, he
places his faith in a power meter and then tells Anakin he's bound to
be the most important and strongest person ever, setting him on the
course to ruin. Everyone's the Chosen One, everywhere.
Old Republic has to fall to give way to the Star Wars universe people
know and love. It was a bloated, complicated mess complicit in some
terrible things (the senate turning a blind eye to slavery, the authors
some really terrible, uncomfortable stories (Prince Xizor remains one of
the worst things they've ever done.) In the decades following Return of
the Jedi, a new bloat formed, with the same focus on mechanical
classification that Qui Gon fell for. It needs to burn down to return
Balance to the Force.
