KV's right about him needing refining. That's what the story is about. It shows us how James Bond became "Bond, James Bond." He's still smooth and still sophisticated, he just needs some polishing before he shines like the Bond we've all come to know. And he gets it throughout the movie, which the ending shows.
It was a good refresher for the 007 series. I mean, invisible cars? Come on.
Oh, and Q and Moneypenny aren't in it because they weren't in the book. But I didn't miss them overly much.
