This books is pretty interesting in how it kinda proves what a troubled mess TROS was. There's barely any mention of Palpatine and no art of him, kinda proving how late of an addition to the film he was. The concept art of Klaud and the Sith Troopers are much more impressive than the lazy versions we got on screen, and the numerous things being taken out and then put back in multiple times makes me want to know more about what the hell was going on during the making of this movie.
