tl;dr: Odds are 725:1 you'll love this book! If you enjoyed Star Wars (IV-VI), if you want to learn about moviemaking, if you appreciate art—you'll love this book by J.W. Rinzler.
I've watched the original Star Wars trilogy too many times to count. My Dad introduced me to the series in the late 80s, and since then I've watched the movies as they were adapted for VHS, TV, LaserDisc, DVD, and now Blu-Ray.
I have strong opinions about who shot first, which of the trilogy was the best movie (this has changed as I've grown), the proper viewing order of all six existing Star Wars motion pictures, and which cut(s) of the film(s) were best (I don't believe the 'original theatrical cut' was the best—and I wonder how many people who advocate such a release realize that there were more than one...).
