Chopping Mall (1986)

  Hey, kids, once upon a time there used to be gigantic buildings full of different stores called "malls."  They were monuments to the hubris of capitalism, sure, but they were also relatively safe, conveniently located places where you could just hang out with your friends.  Until the robots killed you, of course.  Content warning:  moderate gore

A handful of horny teens hang out for a party after the mall closes, unaware that an electrical storm has turned the security robots into low-rent versions of the security bots from RoboCop.  

This is a pretty typical 80s horror.  There's a lot of T&A, underwritten characters, and stupid plot held together by decent effects and a lot of red dye #3.  Toss this on as a So-Bad-It's-Good with a few friends and you've got a solid party flick.  It's currently streaming on Shudder for money, Kanopy with a library card, Tubi, Peacock, Roku, and Freevee for free.
