A group of annoying young people host a party inside of an abandoned hospital. Before long, their night of fun turns into a night of carnage as a massive, steroid-pumped and shellshocked Iraq war veteran mauls them all to death with various pieces of construction equipment. There are a few beheadings, a jock gets nailed alive to a wall, the token black dude is eviscerated with a drill bit, and a ridiculous latino gay caricature is burned alive in a church (how's that for offensive?)
Hazard Jack is a mostly formulaic slasher -- seen one, seen 'em all -- but it earns some points for seeming at least a little self-aware of its function as pornography. Its characters are so over-the-top stereotypical and the titular maniac so obscenely huge and bestial as to indicate as much.
But in the end, for a film like this, there really wasn't enough gore. Everything in the introduction -- from the deteriorating hospital setting to the brute killer's hefty arsenal of killing tools -- make you expect volumes of blood and guts, and yet the gore level is at best average. The slasher is one of the most overdone genres of film ever, and you can't sell one these days without extreme gore and suspense. Otherwise, it really feels like plagiarism.
As a devoted slasher fan, I hope Jack returns for a sequel. But when he does, I hope he's willing to paint the town red.
