Seen it last night. I liked it quite a bit. It was very well done, in my opinion.
If you've ever read any of Asimov's robot novels, go see this. You will recognize several of the characters and situations. It's really a sort of conglomeration of the novels I, Robot, The Caves of Steel, and Prelude to Foundation.. They're not strictly faithful to the books, but I don't think they were ever claiming to, either. It probably as close as you would ever get to a screen version of any of these books.
