What's even stranger, IMO, is that they didn't fix the technical problems with the movies. The snow speeders are still transparent and the Emperor still has little blobs around his eyes, for example. I mean, most of the movies is really good, technically, but the few places where there were problems ought to have been fixed. Hell, they could have figured out how to do some motion-blur on the rancor and gotten rid of the Harryhausen-ness.
