Superman: The Movie is a special movie that perhaps the current generation might find a bit hokey in its innocence, but I think it still holds up pretty well, albeit I’m still not a big fan of some of the goofier moments.
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.
