“The Vindicator” (* out of four) was a mind-numbing, ugly horror melodrama about a sadistic serial-killer who interrupts a live-stream broadcast and challenges its presenters (Anna Green, Dez Kuchiara, Chris Maher, and others) to nightmarish tasks that uncover their darkest impulses and secrets and push their survival instincts to the mental brink. In-your-face imitation of “Saw”, without any hint of that film’s cleverness or craft. For freaks and masochists only.
