Blade Runner - Paul Crowley

To me this is the most pointless movie that we watched, i understand the symbolism, and how the movie questions what it really is to be human. However i found the movie in many ways to be illogical. So by the year 2019 we have created near human clones that are actually robots? What would be the reason for making thses things so human? I just cannot comprehend why this would be done, and it ruins the movie for me as a whole
