“The Ninth Passenger” (*1/2 out of four) was a wayward horror story about a group of hard-partying college students (Alexia Fast, Jesse Metcalfe, Timothy Murphy, and others) aboard a luxury yacht who begin gradually turning on one another when a mysterious “ninth passenger” begins picking them off one by one and they find themselves stranded. Cheapjack production is even further screwed by dumber-than-dumb characters and crude scriptwriting. Re-watch “Dead Calm” and don’t bother being a passenger for this dreck.
