An early entry in the glory days of TV movies that stands well alongside other TV movies on the era. Well acted, very well edited and scored and most importantly written and directed by Frank De Felitta. It ages pretty well and of course has real dog attacks rather than CGI junk animals. For some reason this quality of TV production died out almost entirely in the 1980's when all the elements of craft that this film has vanished really until X Files and other shows brought back film type story telling to TV.
The story unfolds very well and is believable and involving, this should be on DVD and certainly is among the handful of memorable TV movies of any era, it's like a very good episode of the Hitchcock series or Thriller--the Boris Karloff series. Someone at Univeral get this out on DVD like it deserves. This movie will having you making sure you're home before any store closes. James Brolin sweats and suffers with the best of them.
