According to the Bladerunner discussion forum found on Daniel Anderson's web page (www.en.utexas.edu/cgi-bin/forum/anderson.309m.blade), a requirement for an excellent science-fiction film is the use of the classic battle of good versus evil. In order to make this battle persuasive to the audience, the villain must be considered a vile person who would not hesitate slaughtering an entire planet to make a point. A classic example of the science fiction good versus evil theme is the Star Wars saga. In Star Wars the audience knows from the beginning who the totally evil character is going to be, Darth Vader. From the all black costume to the, menacing hiss rasp of his breathing, the audience can at once determine that this is a person not to cut off on the interstate. The movie Bladerunner does not allow the audience to come to this distinction. Near the end of the movie, I felt saddened by the demise of Roy Baty and experienced a large amount of pity for this poor soul. Why was this so?
