Went and saw it last night. The action scenes were well done but I found a large majority of the scenes to be boring. As Guro said, the plotline was all over the place and I really couldn't get into the movie. I didn't see Casino Royale, so maybe that has something to do with the movie seeming to be a bit vague as to why Bond was doing what he was doing. The extent of the backstory seemed to be this one line that kept getting repeated over and over.
I also missed the cool spy cars that were in all of the Bond movies I have seen.
