This film started out interestingly enough. Kevin Spacey's "Prot" presented himself as a likable and quite knowledgable visitor from another planet. Of course, Dr. Mark Powell, played by Jeff Bridges was the all too human psychiatrist, assigned to uncover the inner self of his "delusional" patient. But it was however, difficult to explain Prot's rather unusual characteristics such as his capacity to see ultraviolet light, an arcane knowledge of the stars, and to seemingly disappear at will, among other things. These things were all used as beautiful set-up for a fresh approach to an interesting premise, but then the film suddenly bogged down as if the writers were at a loss and said to themselves "okay, now what do we do?" The film, in my opinion slipped badly starting with the hypnotic trance scenes. So in the end, the viewer was free to fill in the blanks with a personal take on the question of the moment. Was he real or was he Memorex?
