It’s not very often that a movie — let alone a movie trailer — catches me off guard. That having been said, I must admit that the theatrical trailer for the upcoming Thai horror outing “Ghost: The Cinderella” completely took me by surprise. Although it starts out fairly mundane, the clip quickly descends into gore-soaked madness. Not surprisingly, this preview isn’t safe for work, especially considering it contains both nudity and violence. As far as trailers go, it’s pretty effective. God bless Thai horror. They don’t mind destroying your brain for the sake of the genre. Good for them.
