** spoiler alert ** 
 So this was my least favorite Asimov book so far, yet I think it's interesting. I still liked the idea of making robots as complex as humans, and not just a copy of humans or a one-dimensional robotic character. The sex scenes took me aback a little bit because I was not expecting it from Asimov, but I thought it was interesting also. I think robots are still a complex and deep idea that I want to keep exploring in his books.
