of the series doesn't add anything new to the horror genre, but some effective shocks and an above-par performance by veteran actress Lin Shaye mean that it will provide adequate entertainment for fans of the genre.

Although this film is a prequel, it stands on its own — even though some characters and situations are clumsily bolted-on to provide continuity. With a budget of US$10 million compared to the first one's US$1.5 million, it's also slicker, with slightly better effects and scarier monsters.

Most movie ghosts scare their victims simply by showing up, but those in brutally attack their victims, and in some cases, try to murder them. The story, which steals from and , starts with a vicious ghost physically assaulting teenager Quinn (Stefanie Scott) and leaving her in a wheelchair with broken legs.

When the ghostly attacks continue, her terrified father Sean (Dermot Mulroney) calls in medium Elise (Shaye) to send the demon packing. Elise, however, is haunted by a murderous ghost of her own.
