I wasn’t the biggest fan of Land of the Dead when I saw it many years ago, but seeing it again now, I really enjoyed this entry within the Romero canon as the social commentary, albeit in your face, is present and there are characters one can actually care for.
The Amityville Horror Trilogy set released by Shout Factory has one semi-classic movie, a serviceable sequel and a third movie that is downright silly. The set also has a good amount of features to keep you occupied and the first two movies have good audio/video transfers while the third, at least the video, was awful.
