Just saw it. Wow... it's George Lazenby all over again.
Seriously, though, I have mixed feelings about Casino Royale. It was a barely mediocre Bond movie, but a pretty good generic spy movie.
Lots of problems for my particular taste, though. The plot was overly convoluted (starting about halfway through) and there were too many parts that just dragged. I found the whole casino sequence to be twice as long as it should have been, and then again with the hospital/beach scene to be horrendously dreary as well. Other problems I had was that if this was meant to be a "re-start", then the casting of Judi Dench as "M" was a poor idea (and I love Judi Dench - and she was great, with a good amount of screen time in this movie. Mixed...feelings...killing...me). But really - if you're going to have a re-start, then have a damn re-start. Finally, the idea that removing the "gadgets" to make it more "realistic" was somewhat... misguided. It was not realistic in any way, shape, or form (nor am I expecting that from any spy movie, much less a James Bond movie). Needless to say, if "realism" was their motiviation, it failed miserably.
This was no Bond movie IMO, but a reasonable facsimile thereof. It definitely was a pretty good generic spy movie. They had all the great standard spy movie tropes: Ritzy train at night? Check. Goofy slide-out car gadget? Check. Car chase? Check. One-liners? Check.
A lot of the dialogue was really great, IMO (my favorite: "That last hand nearly killed me." Heh). I also found the cinematography to be among the best out of any Bond movie, by far. That whole parkour sequence at the beginning had great wide-open camera shots with long-running takes (no herky-jerky cutaways and shaky-cam nonsense). Further, I found the music in this one to be excellent (and it's rare I notice music in a Bond movie). No surprise though - it was composed by David Arnold (Stargate, among other things).
