Revenge is sweet, just like Valentine’s Day chocolates. At least, that is what a vengeful, Cupid-masked killer thinks. Be my Valentine … or else. Broken hearts and other mortal wounds await a cast of contemporary young stars when they play dating-scene veterans dying for love in this humor-laced, twist-filled thriller cleverly directed by Jamie Blanks (Urban Legend) and starring David Boreanaz (Angel, Bones), Denise Richards (Starship Troopers), Marley Shelton (Scream 4, Planet Terror), Katherine Heigl (Grey’s Anatomy) and more. Cards, candy and flowers are nice. But for fans of stalker-shocker terror, there’s nothing like a Valentine.
