That doesn’t look good. Keep in mind though that the blu-ray image appears to have been zoomed in, so it’s hard to say. Why is the iTunes HD copy different? Did they release a better version in HD? This may be an example of a really bad transfer in the early days of blu-ray that got remedied years later. This happened a lot, two that I can think of that were released in poor quality and then remedied later were Gladiator and Lethal Weapon.
The iTunes is I think a different resolution. Bluray screenshot is not zoomed in. That’s how it really looks: http://images3.static-bluray.com/reviews/8452_13_1080p.jpg
So, not only has the film been shagged by DNR but it’s also the wrong aspect ratio.
