^ Yeah, that was how I looked at it, the fact that it was a novel and I was getting the whole story. However, I would now prefer to experience a story written for a movie via the movie experience than in the novelisation. That's no disrespect to the format or the writer; I'd prefer to read an original novel before seeing its movie adaptation.
Like yourself, I also read TWOK before seeing the movie; I also read one of those photobooks that they used to make. I also read ESB before seeing it and read the comic adaptation of it.
