I have to agree to some level with the general sentiment here. I have the "Creating the Worlds of Star Wars" book, which is super wide and has 365 "spreads" and I turn every so often like a page-a-day calendar you turn very sporadically. It's in 7 sections, one for each movie and a section for all three 1997 SEs. I really, really, really enjoyed turning pages the first half of the book. Even the SE stuff was interesting to see and read about. I considered not continuuing once I got to the PT, but from a technical standpoint, it's still very interesting to see how it was all done.
I don't like the movies, but the behinds the scenes stuff is still incredible.
