This was a very frustrating movie for me. It was way too different from the book and I kept waiting for the story line to match up. It never seemed to, so I got confused and mixed up a lot.
I think that if I had not read the book, this would have been a movie I would have sat through if I had nothing better to do. It wasn't the worst one I have ever seen, but it was not even close to a good one.
I hated the fact that there was so much emphasis on fighting, not on the contervsy about robots and humans surpassing them. Also, by having Batty actually kill someone because of anger, that did not help the idea that robots could be humans. Plus, I seemed to see emotions coming from the robots.
