Upon re-watching Blade Runner, I decided to give the novel 3 stars instead of 4, because the film was much more enjoyable and it also had Harrison Ford in it, an actor I appreciate a lot. 
 The book was good, too, I'm not saying I didn't like it, but there were some plot twists I disliked. (view spoiler)[For example, Rick didn't seem the type to sleep with random chicks, especially if said chicks are much younger than him and are FREAKING ANDROIDS, FOR GOD'S SAKE! (hide spoiler)] 
 It had many philosophical ideas among its story, the most important one being 
 Everything anyone's ever thought is real. 
 Kinda disturbing, right? 
 There were not too many major characters, except Rick Deckard and (maybe?) Rachael. I didn't like this too much, I'm used to read about many characters who have exciting story lines, and when it comes to this, Androids was not exactly for me. 
 But I liked the themes, and Rick's story. He was trying to save his wife from mental illness by getting the money to buy a real animal. To get the money, he had to "retire" androids. That means, basically, to kill them. The idea for the novel is great, I think, but the writing could've been better. I believe I didn't find it easy to get into it because I haven't had much exposure to Philip K. Dick's work, but I'm going to catch up as soon as I can.
