Melanie Griffith and Matthew Modine finally get to purchase their dream home atop a gorgeous San Francisco hill. With the expense of the house, however, comes the need for a tenant, which is what inspires them to seek a renter for their basement floor. Many apply, but the most seemingly perfect candidate is Michael Keaton who moves in immediately. Unfortunately, he turns out to be psychotic, and the happy couple are forced to react immediately. The script has a few more nifty tricks to it than most conventional Hollywood thrillers, especially centering around horror stories involving tenant/owner situations (I'm sure many people can relate to a lot of things that happen, and many people would love the end of this movie to happen to their renters). On the other hand, it's not all that exceptional either, and while Keaton enjoys chewing up the screen, Modine and Griffith never get to really show off their amiable personalities. The liveliest moments in the film come between Keaton and a fantastic but little seen Beverly D'Angelo in an unbilled role.
