One of the first entries in a thriller sub-genre which
seemed to saturate the early 1990's. It works reasonably well due to Michael Keaton's subtly chilling performance as a nightmare tenant who makes a young couples life hell when he moves into
the spare room of their luxurious three-storey semi, using every trick in the book to withhold paying any rent before his true psychopathic tendencies come to the forefront.
The finale descends into cliched and formulaic melodrama
which the build up didn't deserve, harming what could have been a very good psychological thriller, despite some very good performances from its cast throughout, particularly Keaton in a role
which was rather cast against type at this point in his career.
