I agree that HDTV version seems better - I like its color grading better; but IMHO it's more due to the fact that BD is softer, and seems out of focus... just a proper sharpening (that is not harmful as when used with film), a ColourMatching touch (to get the HDTV color grading) and you should admit it's better than before...

even if it still lacks a bit of detail in comparison to HDTV, almost surely a byproduct of excessive grain removal; but BD has more image on top and bottom...

What do you think?
