Oh wow, I guess we have spoilers on a movie that is 25 years old... Hey, guess what, Darth Vader is Luke's father! w00t!
The Workprint is nice, some of the cuts aren't great and there is temp music towards the end (Workprint, DUH!), but it doesn't have the "vision" and it sticks with the intended ending. I'm sure some of you have seen this in bootleg before (I had only ever read about it), and while the picture isn't always great and the sound suffers from time to time, its worth watching. The commentary track is, well, meh. I won't be listening to it again, I got out of it whatever there was to have.
I'm onto the writers'/producers' commentary track now. Better than Ridley's, but unfortunately they were not all in the same room together when this one done. Its a writers' track mixed with a producers' track, so you really miss out on half the commentary from each.
