I think this movie was totally underrated. Malcolm McDowell's performance as Dr. Russell was brilliant. His personality transition during the course of the movie added a wonderful level of humor. I enjoyed the story line and found that the whole plot wasn't given away too early. To me, the movie was just what I think it was intended to be--light entertainment. Also I felt the Geoffrey Lewis's part as Michael added much to the overall story. He was the "straight man" and pulled of some great deadpan lines. One other bonus is that the movie shows that very fine line between sanity and insanity. I could watch this production a second time and be just as entertained.
