In 1965 one of the world's top directors cast one of the world's top stars in an oddball B&W horror film called REPULSION. The film was a major international success, and also set the standard for creepy horror films following a lead actor (usually a pretty girl) performing daily tasks in a really creepy house. This genre was especially appealing to first-time film-makers because the ingredients were so basic -- girl, house, camera, film, script. Dozens of these kinds of productions were done in the following decades --- culminating with the bizarre CHRISTINA'S HOUSE (1999),which added a new ingredient to the mix, a serial killer hiding (literally) in the walls of the house. MOTION DETECTED can be considered a throwback to this style of film-making, with "technology" filling in for the serial killer. Everything about this film could have been done so much better -- the script especially. The end result, however, is a herky-jerky production that fails more often that it succeeds. Nostalgia lovers only. ((Designated "IMDb Top Reviewer."

Where to start. First of all, the movie makes zero sense. This is not a "if you pay attention, everything makes sense" movie. This is a movie with zero internal logic, no explanations for anything, and no actual revealed motives. There are also dumb coincidences. The leads are a couple who escaped a serial killer called El Diablo and end up in a home with a security system installed by a company called Diablo operations or Diablo security, something like that. You might think they're connected, which would be stupid. But it turns out to be just an unbelievable coincidence. Which is also stupid. This is literally one of the worst movies I've ever seen.
