I keep a copy around mostly as a cautionary tale for family members considering watching a prequel. The upside of the kids only having watched the OOT and the Disney films is obvious – but the downside is that they really don’t know how bad some parts of the Star Wars catalog can get, and could naively end up watching ROTS if they’re not careful. Show them the Holiday Special, assure them all of the prequels are much, much worse, and now they’re pretty safe without any of the pain and scarring. It’s a prequel vaccine, basically. A little cowpox to prevent smallpox.
