The movie I watched was “Her” (2013). The best part of the film was that technology was undeniably present, yet at the same time it was incorporated seamlessly into the lifestyle of the main character.
A small design decision was that everything that was technological in this film was almost entirely voice-activated. There is no keyboard or mouse for you to interact with the technologies used in the film. Through this subtle removal of technology as opposed to only introducing new ones, the film was able to bring out a very important dynamic that the main character, Theodore, has with his artifical OS girlfriend, Samantha — reliability.
It was also believable due to the way voice activation was portrayed which isn’t far fetched as one might think, as we imagine the way technology tends to be handled in our world and possibly in this type of future.
