I'd have to go digging, but I once found a scan online of one of Lucas' original scripts.
It was AWFUL. Like, imagine the most poorly written teenage fiction, run it through Google Translate into another language, then another, and then back into English. That's what you would get. As I understand it, the actors did a LOT of ad-libbing.
I'm a pretty big fan and f the movies, but I've never really read any of the novels or comics.
When I heard they were making VII, I cringed, having been burned by the prequels. (Seriously, I kept wanting Baby Vader to get sucked into one of those podracer engines). Then, my buddies and I went and saw the film. At the end, I was cheering.
Oh--and Finn and Poe are OTP.
