APT - High rise horror

This is another in a long line of long black haired, evil women who seek for vengeance horror flicks. The Ring and the Grudge were successful because they blended elements of old ghost stories into a contemporary setting; with few exceptions, everything else that has been influenced by them are cheap, weakly directed imitations. APT at least tries to borrow from different sources -- Rear Window, Misery, and One Missed Call, but fails to use them effectively. A designer who lives alone in her high rise apartment encounters a woman in red in a subway, who commits suicide and tries to take the designer with her. Meanwhile, people in her high rise complex are mysteriously dying, at the same time each night, after the lights mysteriously turn off. A woman who looks similar to the woman in the subway lives across from the designer, who can't walk. Her parents had died in a freak car accident, and she lives alone, but is being taken care of by all the neighbors. They become friends, but unbeknownst to the designer, her friend is being abused by all those who are claiming to help her, an outlet for their own desires. And there is a crazy guy living in the building as well. What's the connection? You'll be disappointed when you find out. It should have been a more interesting movie, but it isn't. Tired cliché suspense build ups, weak main characters and plot twists sink this film. Pass this one by.
