Derivative or Innovative?
In the 24th century, people are irrelevant. Why does society need more people when there is overpopulation, a shortage of resources, and above all, machines to do man's work? But humans being the physical creatures they are, desire love, family, and sex. OK, you've seen these themes repeated many times in the movies, e.g., Sleeper, THX-1138, Logan's Run, 1984, even AI. In James Avalon's adult film, Taboo 2001: A Sex Odyssey, you see two of these themes being repeated: repression of sexual drive by pills, and thought control/monitoring. Are we destined to live in a dystopian future? According to the movies, yes.
In spite of all the similarities to pre-existing novels and movies, DOA Final is still fun to watch. It is hard to be original when so many people seem to dream the same dream. A kind of collective consciousness in our species, oui?
Anyway, in this strange noodle soup trilogy of movies there is a common bond. At least one. It is the need to destroy and to build, in not so many words. DOA 1: Yakuza/triad war, good guy cop vs bad guy, order vs. disorder. DOA 2: same guys again but as hitmen, but with a conscience. They donate their fees to third world nations. From destruction (killing) to rebuilding. DOA 3: the consciousness of the two protagonists have been cloned into killing machines (replicants). Then the killing machines get upgraded a generation or two. And damn, the replicants develop a conscience, and do the human rebels a favor.
