--(hopefully) final edit--
Just finished watching this - it's very, very well done. There's a noticeable drop in quality in the shots not from the HD broadcast, but there's only, what, two of them in the movie? It's not bad at all, and not terribly noticeable on an SDTV anyway.
Menus are, of course, top-notch, and the "scope" music video extra was a nice touch. (Glad I was able to help with that, Ady!)
But the real stand-out of this disc is the laserdisc's 5.1 track - holy Christ is it good. Unless you saw TPM in a 5.1-equipped theater in 1999 (I didn't), or had the laserdisc and a player equipped to output 5.1 (I had neither), you've never heard TPM sound this amazing. It blows the DVD audio out of the water in every respect.
Bottom line, if you're a purist and a completist like I am, this is a must-have. Regardless of your opinion of the film, it's almost indisputable that the changes made to the DVD release hurt the film's pacing quite a bit. This is no longer the case.
Another stellar Adywan release! Highly recommended!
