The problem I had with the book is that after so many other books and movie have come out, the original message of this book has been done so much better. The whole "Are Robots/Andr-Gynoids human?" Unfortunately very few characters in this book actually got much of a personality for me to really care about them. The only major ones are Deckard, Rachael Rosen and Isidore. The other androids seem to get some kind of "plug and play" personalities (the wife, the cruel one, the human-est one), if even that. Even Roy Baty is barely described. The movie does a better job at giving them purpose but even then poor Baty/Batty is only given a basic "want more life, kill kill kill" responses. There wasn't a time when we see them trying to integrate into human society and succeeding failing. That was established that Luba Luft was doing good for herself while the rest were either dead already or playing with Pris's TV/kipple.
Overall I just couldn't feel (have empathy for) any of the characters in the book. They felt very cardboard. Even the movie can't really save this one.
