Amityville Cop opens with an adequate kill scene reminiscent of the original Maniac Cop. We are then treated to a horrible comedy scene between our main character Detective and his captain with a bizarre swing music soundtrack.
The rest of the runtime consists mostly of very stilted dialogue scenes shot in the police station (someone's empty house), stock drone footage, and non-gory kill scenes.
The casting of Laurene Landon as a cult leader solidifies the Maniac Cop 'inspiration'. Cult favorite Lisa London also appears as the only two notable faces on display. The rest of the cast are regulars of Hatanaka's other films and little else.
Speaking of director Gregory Hatanaka, he was also the director of the abysmal Samurai Cop 2 along with a number of small films, but seems to make his living as a distribution consultant on larger films and somehow was a music supervisor on Kill Bill.
Most recent Amityville films have little to do with the house, but there seems to be no tie whatsoever with Amityville Cop. It's not even a good sequel to Maniac Cop either.
Bottom line: boring story, bad cast (especially the lead detective's terrible attempts at being funny), little action or kills make for a very bad film. Still, at least the runtime is a mercifully short 68 minutes and it's not the worst of the endless Amityville films (Amityville Witches or Amityville Vanishing Point earn that title... for now...)
