Iam a big fan of Gregory Harrison and this is his best film. This film is not to be taken too seriously as some of the emotional scenes seem a bit slapstick however the story is good and Harrison's protrayal of obsessed Robert Kenzer is very realistic. Kenzer has a relationship with Sharon Blake which turns sour after Sharon finds out what sort of man he is. He is unable to cope with the breakup and his obsessive compulsive behaviour starts to cause problems for Sharon and her everyday life. A very good realistic thriller.
