Sum up- Are you an Asimov fan? Are you looking for this book adapted to the screen? Dont bother looking for a careful adaptation of the novel. Matter of fact, dont expect much in the way of the novel, except for some characters and the three laws. Didnt read the book? It might help you out. This is a good movie and you can avoid the problems of film and the lack of a careful adaptation. I liked the movie and I would be happy to see it again. I was concerned with the lead actor's abilities and too much CGI as a possible, yet probable angle where the film would fail. Will smith's one-liners didnt detract from the story, and neither did the CGI. Like most movies, you get the hint of character complexity, and they do this well for a movie, but the story is well put together. Personally, I found the movie to be more provacative than entertaining, and stimulated a suprisingly very wide range of discussions afterwards.
