The Dark  (1979)

Theatrical Release Information:
The Dark

This well-acted but wildly disjointed sci-fi/horror film stars William Devane as a writer who takes a personal interest in a series of baffling decapitation murders in the L.A. area, all of which seem to indicate some kind of supernatural force at work. He is joined in his investigation by a TV reporter (Cathy Lee Crosby), while detective Dave Mooney (Richard Jaeckel puzzles over evidence that the killer may not even be human. Their subsequent monster hunt is both stylish and suspenseful but completely collapses at the end, trashing any attempt at explanation by revealing the murderer as a lumpy-browed alien brute with ill-fitting slacks and laser-beam eyes. After a tension-filled 80-minute set-up, the moronic climax brings the suspense to a jarring halt and was probably added late in the game by a lame-brained studio executive who decided in mid-production to change the killer into an alien. Directorial duties were originally assigned to Tobe Hooper (The Texas Chainsaw Massacre), who bailed out early to be replaced by John "Bud" Cardos. Enough said. ~ Cavett Binion, All Movie Guide
