When audiences turned in to the ABC Friday Night Movie on October 29, 1976, they got to see the sequel to one of the biggest horror films ever. However, what they ended up watching had little to nothing to do with its inspiration, 1968's Rosemary's Baby, or the Ira Levin-written sequel Son of Rosemary.
It probably goes without saying but Rosemary's Baby was a film that did not need a sequel. It ends on a tense yet perfect note, to elaborate further just seems misguided.
Yes, terrible - scripts, writing, dialogue, plot, acting, cinematography - you name it. OH.
