The iconic status of Blade Runner will certainly be reinforced by the sequel. Although towers of ilium has been critical of the original movie in the past, its visual significance is not to be scoffed at. Ridley Scott will pull off something impressive again, but in the context of modern CGI artistry, that type of visual "wow" is becoming standard fare.
The role of the cyborg/android in modern culture is showing real staying power. Westworld will only grow more popular.
