This was released in the early days of "WTF!? This doesn't look like the discovery channel!" reviews. It didn't take an inordinate familiarity with the film to realize the differences in the HD presentation, when the sd was readily available to a/b on the flip side.
Another thing that I think was a huge factor in all the pot shots this took, was that format warriors found titles like this easy to slam since unlike the majority of Bds at the time, it was over 10 years old and was never known for being a particularly 'pretty', let alone splashy looking movie.
I won't be suprised if the film looks 'different' on Bd. A change in the films color timing would accomplish that. That won't mean it's more correct. I'm sure they can now feel free to DNR the hell out of it, since most of those bad reviews singled out the graininess of the image.
Let's put it this way, the current HD DVD is the antithesis of the New Line Pan's Labyrinth. You guys can have Pan, and the rest of the DNR'd monstrosities to come. I'll keep AWIL.
