The Blu-ray has a slightly different framing than the DVD throughout. The DVD has less in the horizontal, while the vertical framing is just shifted. The BD does appear to have some edge enhancement; not much haloing but overly sharp faces.
I can barely see any difference between the 1080p and the 720p downscales even at 200%, and these are the most detailed shots I could find. Clearly superior to the 480p though, so around 720p level of detail.
I had higher hopes for this disc. This movie isn't that old, so I think a remaster could improve a lot in the resolution department. I don't see why they would drop the isolated score/commentary, and not including the theatrical trailer is just strange since even most barebones DVDs have them.
Strange thing I noticed watching this now, there are shots of LCD TVs that show massive interlacing "comb" artifacts on their screens. Were there LCD TVs without deinterlacing in 2000? Or were they computer monitors standing in?
The Blu-ray looks clearly superior to me. No complaints from my side. The noticeable difference between 480p and 720p is huge compared to 720p and 1080p with just about any material in my opinion. It's the law of diminishing returns (unless you are projecting on a absolutely huge screen).
