It was fun! More like a book of puzzles relating to how Asimov's Three Laws of Robotics have caused a problem, how the characters take advantage of the laws to solve the problem, and what it suggests about HUMANITY ITSELF! I think this would be a good one to read one chapter at a time over the course of some months, rather than all in one go. (Oh and there is a eye-roll-inducing line about the otherwise estimable Dr. Calvin when "some of the woman peered through the layer of doctorhood" and she worries about being beautiful or not, but hey, 1950!)
