I first saw THE STEPFATHER on cable TV. My memory of it has always tied in with something else I was doing over the Memorial Day weekend in 1987. But its listing in IMDb is curious. They show an LA release date of January 1987, a NYC one in May, then what I guess might be a general release one in June. Well, maybe my memory placement of it is wrong. On the other hand, interesting things would occasionally happen in those early years of cable.
Anyway, I've always meant to watch it again but that is still my only time to have seen it. I have no memory of the music, crappy or otherwise, but I was thrilled and chilled by that sucker and I've never forgotten it. When a remake happened, I had no interest whatever in seeing it. I do need to revisit the original sometime.
