Amazing world-building. Reading about the "caves of steel" in which Earth's population locked itself gave me a very claustrophobic feeling. As someone who lives in the country, it was hard for me to grasp the instinctual agoraphobia of these people and its description gave me a very creepy crawly feeling.
I liked R. Daneel Olivaw a lot and sometimes it was hard not to forget that he was actually a robot. Well, until he was willing to let Elijah take the fall to serve the "Greater Good", that's when it really hit me that, as likable as he was, Daneel was still a robot without feelings. Elijah, on the other hand, was a bit too emotional for my liking, perpetually afraid or angry. Also, as an agnostic/borderline atheist, I didn't like his obsession with the Bible, it felt really... preachy in places.
Still, a great book, exactly the kind I like - a sci-fi that's about exploration, not just shooting at each other.
