the 4th floor be a decidedly mediocre film star juliette lewis a a young interior designer with a heck of a problem neighbor . jane ( lewis ) have recently inherit a terrific 5th floor apartment from her grandmother and and per agreement with the landlord and get a ridiculously low rent rate . her boyfriend ( william hurt a a creepy weather man ) want her to move in with him and but she want her own space . so she move in and and weird stuff start happen and and because this be a b grade horror flick and there a dumb and not to be find in reality reason why . a the none too intriguing jane keep try to tell others her boyfriend and the police and coworkers what go on and everybody think she lose it . so and of course and she have to face the problem the lunatic living right below her alone . neither scary nor interesting and the movie single save grace be lewis . she a very fine actress but poorly use here and which be not to say she isn not the best thing about this flick because she be . she have feral charisma and hold the screen well than a dozen of the silicone bimbo that routinely populate this type of movie . this type of movie and though and be not worthy of her which be ironic and give that she probably the only reason anyone would see it .
