When you look at Blade Runner, which looks outstanding, from what I've seen of screen shots. A 25+ year old film, that looks far better than many newer films, it shows what can be done. The amount of complaints that the LotR theatrical version BD's had, not just because they decided to release the cinema versions first, but also the PQ, shows it was way to get desperate people who wanted LotR on BD badly, to part with their cash. There were some people who tried to justify it, by saying they didn't like the extended versions, and preferred the theatrical versions instead. That's fine if both releases have the same PQ, just theatrical and extended versions, but if the extended versions get a make over, that will surely annoy the people who bought the theatrical versions, knowing they wouldn't want the extended versions.
Question is, assuming there is a remastering. Would that remastering still have been done if no one had complained about the quality of the theatrical BD release? or was it planned all along? Obviously, will have to wait until nearer the time, to see if they do remaster it.
