I am a little disappointed in myself that I hadn't read this book until now (since I have been reading sci-fi for 30 years). On its own it is very well written except for a few pieces of stilted dialogue. The characterization was amazing for a set of short stories and the stories tied together nicely.
As someone with a very analytical mind I loved how each story boiled down to figuring out how the Three Laws were interacting and causing unexpected behavior in the various robots. I really like the concept of robopsychology as a discipline but wonder if it could exist outside of a world with such strong restrictions placed on all robot brains.
The fact that these stories were written between 1940 and 1950 makes them all the more intriguing to me. I am impressed that Asimov wrote about hyperspace travel and elegantly wove it into a story.
If you saw the Will Smith movie of the same title but haven't read the book then do yourself a favor: read the book and pretend the movie had a different title since they have nothing in common but the Three Laws of Robotics. The movie was a simple murder mystery but the book is a rich history of a world that might have been.
