And this is a horror movie? I think not. A group of young, hormone-driven teens, sneak into an abandoned asylum (which is basically just a really old house as there are no cells in the so-called "asylum"). And they decide to play a game of "hide the undies" from each other. The kills are totally unoriginal and stupid. Many sex scenes, which I would normally consider good, but are just stupid and pointless here.
To be brutally honest, I can't even remember what Corbin Bernsen and Dee Wallace Stone had to do with the film, I kept on losing interest. I even started dusting the TV screen when it wasn't dusty. That should tell you how terrible this film is. If you haven't seen this, please don't. It may be dangerous to your health. The bottom line: "Bring this film to the garage and smash as many times as you can with a sledge hammer". KILLER INSTINCT gets 1/2* out of 5.
