Chewie was given the pieces of C-3PO by Darth Vader in ESB!
huh? That makes no sense at all. We clearly see Chewie stumble into the incinerator room and grab the big box of parts.
and Gomer, you talk about how the new additions challenge the creativity of the viewer and all that stuff, but I'd have to say I think it's just the opposite. When there was only the OT, people could be as creative as they wanted with the backstory, and nobody would be wrong. Then the PT gets made and says, "No! THIS is what happened!" Which is more challenging to the viewers' creativity?
