25. My Bloody Valentine (2008)
Director: Patrick Lussier
Stars: Jensen Ackles, Jaime King, Kerr Smith
Throughout the technology's history, 3D has been both best friend and worst enemy to the horror genre. Patrick Lussier's remake of the '80s slasher classic about a mining community being savaged on Valentine's Day belongs, fortunately, to the former category. Because if the use of 3D in the world's best amusement park rides has taught us anything it's that sometimes a little exploitation of the medium—where it's used strictly for its ability to create in-your-face visuals—is a welcome respite.
My Bloody Valentine also holds the distinction of being the first wide-release, R-rated movie to be shown with Real D technology. Let the bloodbath ensue!
