I love the movie very much in general. The scenes of the movie are pretty intriguing – the world is like a twisted big wasteland with large buildings, dark wet streets, strange lightings and dense crowd. One  big difference from the book is that it doesn’t focus much on describing the importance of having a real animal which means you have humanity (vanity). But there is one scene when Deckard asked Zhora if her pet is real, she asked back how a real snake is affordable here. This could be counted as a little hint. Sebastian could be considered a s counterpart in the movie (Methuselah Syndrome) to Isidore in the novel (genetically degraded) human beings. Isidore lives alone in an entire apartment building. Sebastian uses his talents in genetic design to create automata companions. It depicts an atmosphere of loneliness that modern technologies bring.  In both movie and book, what surprises me is how they treat androids as pet, something seems ok to be hunted and killed. The idea of robots showing emotions has always been intriguing and make me a little scary. It also reminds me a movie called Ex Machina, where the owner treats the robots he make as sex toys or experiment tools and eventually got killed by the robot who is programmed to practice the goal of escaping.
