YMMV / Derailed (2002)

• Complete Monster: Mason Cole is the leader of a gang of terrorists who aim to create a cure to a lethal strain of smallpox, not out of any humanitarian effort but solely for the profit involved. To procure the virus, Cole hijacks a train and shows the kind of man he is by smashing an antique violin after waxing over its beauty. Mason murders a random passenger the second they can't provide the information he wants, and heartlessly kills one of his own devoted partners when he learns she's contaminated. Mason has no hesitation leaving every passenger on the train to die of the virus when it breaks out, nor does he hesitate in trying to kill hero Jacques Kristoff while risking the smallpox infecting millions more, attempting to murder Jacques's young son in front of him out of spite.
• Special Effects Failure: The movie's CG is shoddy and borderline bargain-bin level, with a helicopter explosion notably looking like a cutscene from the original PlayStation.
