There are numerous bloody deaths throughout the film: stabbings, stranglings, a drowning. A man is shot in the arm. A woman is shot and killed (we don't see the wound). The more graphic deaths follow:
A man has his face burned in a fire and we see his skin "melting" (the effects are cheap, but the implication is a disturbing death). A woman is stabbed in the eye with a sharp wire when she peaks through a keyhole (we later see her eye on the wire). A girl is caught in a trap that pulls off her legs, we see only the aftermath (her body on the ground, and her severed leg hanging from a rope).
The effects are not particularly realistic, and the camera usually doesn't linger on them long.
