As Seen In: Ghost Ship (2002)

Take your pick as to which one of these scenarios is worse. Exhibit A: It's nighttime on your vacation cruise liner, and all of the vessel's occupants are crowding onto the dance floor to let loose . Suddenly, a long, inescapable wire swooshes through the crowd like a jump rope, bisecting each of the dancers and leaving one nasty, crimson-covered pile of mutilated corpses.

Pretty bad, right? Now consider this: You could also be the sole survivor (like the little girl at the beginning of Ghost Ship). The only reason you're alive is that the ship's captain protected you, but when the massacre ends, the top half of his head falls to the ground right before your eyes. A year's worth of therapy sessions wouldn't even begin to remedy that memory.
