I am a fan of Science Fiction and I disagree with all the negative comments below. This story was never meant to be as heavy as 2001 or even Ground Hog Day. The actors are not preforming Shakespeare. They do a very good job in this light drama, perhaps more a kin to a tv movie. Helen Slater gives a very subtle and nuanced portrayal of a woman who is deeply lonely and yet still open to a man who sincerely cares about her. The story focuses on the characters and their interaction and does not spend an inordinate amount of time on explaining the cause of the time displacement. This is one of the best science fiction movies I have ever seen because it is honest, simple, and done with care. I doesn't bother me that it obviously had a low budget. Besides, the whole thing essentially takes place on one floor of an office building.
