Blu-ray grabs taken from The Hitchcock Zone:

The HDTV broadcast is covered with grain and also has a slightly larger vertical image (compare the vertical cropping of the hotel room and office shots in the Blu-ray) and there is marked difference in monochrome tones between the two.
I know that despite what Hollywood execs and some websites would have us believe, many films are simply grainy by their nature because of the film stock that was used (Aliens, Predator) and were never meant to look over polished, glossy and pristine. With this in mind, which is a more accurate representation of the film, the smooth, softer looking Blu-ray or the grainy HDTV airing?
I’d be interested in your opinions.
