Well, someone may say that we cannot judge a Blu Ray for screen captures.
http://www.dvdbeaver.com/film/DVDCompare6/jaws.htmThe image do not look verry sharp or film like for me. Looks like excessive or not optimal grain reduztion filter was used.
It's not bad, but it's not great, at least for what the screen captures show us.
Have anybody watched this Blu Ray of Jaws ????
Maybe it's another case of screen captures do not make justice.
Keep thinking...
