If you’re down in the dumps this may not be the movie for you. Unless… you, like myself, enjoy (if that’s the right word) the cathartic feeling of watching a deeply sad motion picture.  Let’s face it, a movie about the extinction of humanity due to radiation poisoning where Fred Astaire suffocates himself in his car and Anthony Perkins, his wife and baby daughter take suicide pills before the fallout kills them is hardly likely to give you a spring in your step.
