Martin Campbell, who also made 'Goldeneye', was an excellent choice and, for me, is one of the best Bond directors. The action sequences are brilliantly shot and edited for maximum impact and are some of the best out of any Bond movie.
The tone is much edgier and nastier than the Brosnan movies, harking back more to Dr. I saw this at a cast and crew screening in London last weekend: I'm not a huge Bond fan, but I do enjoy them on a purely popcorn level and this was definitely one of the best in recent memory.
