One subgenre that consistently contributes more than its fair share to the quality of world cinema is the protoslasher that references real serial killers. While arguably less focused on real-world crimes than The Zodiac Killer (1971), Dave Adams's Another Son of Sam (1977) is a sincere and successful attempt to scare its audience by showing them that dangerous killers can exist in even the most mundane places.
Some critics are oddly unimpressed with Dave Adams's vision of realism. For example, reviewer Wizard-8 writes, "For the most part this movie will test the patience of even the most forgiving viewers." Reviewer snicewanger writes, "I don't know whose idea it was to make this film, but they should be locked in a padded room." And reviewer jellopuke is so unimpressed, I will quote the entirety of their misguided review: "This is incredibly amateurish in all ways with a terrible script, terribly edited (with strange freeze frames everywhere), terrible actors giving terrible dialogue, and a beyond boring pace. STAY FAR AWAY. This is 75 minutes of your life you will never get back. Do ANYthing else with your precious time on this earth. PLEASE."
In actuality, one could hardly find a more productive use of 75 minutes than viewing Another Son of Sam. Read on to find out why...
