I think Anchorhead should start a website called www.originalstarwars77withaspectsoftheempirestrikesbackallowedbutverylittlereturnofthejedi.com. He could then have a subsection that allows for Zahn EU :)
He does always provide good insight, I must agree. I think it's interesting that Tarkin's role is not really replaced in ESB (the Emperor and his influence are present, but really Vader is the scary baddie in this movie). However, Boba Fett's frief appearances are in a similar vein, as Fett shows no fear when addressing or being addressed by Vader.
Unlike many on this site, I really enjoy ROTJ, but I do wish Vader were still a stronger character. He starts out tough when addressing Jerjerrod, but Palpatine comes and it's sissy Vader from then on. I wish we could see the defiant Dark Lord who was secretly willing to overthrow the Emperor or something. I guess that would give away the power of the moment when he hurls Palps down the shaft, but still, I just wish he were a tougher guy, and for that reason I actually wouldn't mind seeing the choking Jerjerrod scene reincorporated.
I like movies that show multiple villains with different roles. I like the trio in Raiders of the Lost Ark.
