Edit: I didn't name this? I are dumb.
Now before you jump down my throat I'm not saying it's bad, the original trilogy is good for the most part but it is not the gold that people seem to view it as. There are many good parts but there are bad parts as well.
I know someone will say in response to some of my criticisms: "in the novelisation ..." I don't care. I doesn't matter what the novelisation says, the movies are what matter, not the novelisations of the movies. Another response will be: " In this expanded universe book, video or game ..." Doesn't matter. Any expanded universe story from any expanded universe would at best be ambiguously cannon, any story from any expanded universe will never be truly cannon whether it's for Star Trek, Doctor Who, Warcraft and even Star Wars. And I don't care what George Lucas has to say on the subject, it's doesn't change anything, any story from any expanded universe will never be truly cannon. Star Wars geeks and EU writers need to remember that and the fact that any expanded book is just glorified fan fiction.
Personally: unless it's a parody or a deconstruction I hate fan fiction. Write your own story, it's okay to take inspirations and ideas from other stories but make it your own.
Lets look at the original trilogy.
