All the films that fall into that general category of “cool when I was in elementary school” have this common peculiarity. I, as well as most of the people with whom I saw them, remember one or two particular scenes from each movie, and not much more up until we start watching again, at which time the floodgates of memories both shameful and grand are thrown open. With Sword and the Sorcerer, for example, everyone remembered the slimy wizard making the witch’s chest explode, and everyone remembered the steamy bathhouse scene, but not much else. In the case of Beastmaster, another classic from a bygone era, we each remembered some green guys who wrapped their leathery wings around people and dissolved them, and we remembered Tanya Roberts bathing nude under a waterfall. In Revenge of the Ninja it was a tremendous spray of blood as Sho Kosugi kills the villain at the end, and two naked people getting killed in the middle of having sex in a hot tub.
There may be a pattern here. I’m not sure.
