Silent Hill. Worth the matinee price. Although it should've been called Run, Radha, Run. The plot was pretty boring and the climax...meh. But oh my fucking god, the visuals. I haven't been so impressed with costumes, set design, and fx since The Cell. In fact, if you replace the mutants in The Hills Have Eyes with the demons from Silent Hill you'd have a nearly-perfect horror flick.
My favorite things about Silent Hill? Radha Mitchell. Hot blonde motorcycle cop in leather pants. The metal-mask demon shucking a girl like an ear of corn.
