A science fiction classic, I liked this better than I thought I would, and a lot better than Asimov's other big classic Foundation. 

I, Robot is a collection of short stories, something I didn't know ahead of time. The stories vary in interest and quality, but overall are good. This book is the source of the Three Laws of Robotics, and each story, excepting the first, explores different ways robots interpret these laws and can go wrong from them.

I enjoyed this pattern and trying to figure out why the robots behave a certain way before the mystery is solved in the narrative, as it always stems from some form of logic of the laws. There's also slow development of the world as the technology progresses and the laws begin to be expanded on or altered in certain ways. 

The story is also notable in that it doesn't involve robots turning upon their creators in a sinister uprising. The threat of a rogue robot is used only once, and for the rest the First Law of never harming humans isn't threatened. The concluding story had a rare optimistic viewpoint on robots surpassing humans and running everything better, and the book was a novelty simply for having such a viewpoint.
