Death Spa (1988)
Watched this purely because of Brenda Bakke
An AI controlled gym goes crazy and starts killing people. People die. It also possesses people at a point.
Not a bad one really, cheap sets and props are showing, but the effects aren’t too bad. Actual explosions and decent makeup effects. Lighting is bad, but that’s par for the course.
The exact same plot would work even today, maybe someone will do a remake?
Not something I would ever watch again.
