Isn't David Arnold doing all the music again? I hope he does a good job, because he makes a lot of 'filler' music for the films, which is just plain boring, dull and crap. I hope he does a good job with this one.
When the theme played I actually cringed a bit. I guess it's the classic guitar. I know it's the original instrument for the theme, but I don't like it anymore. I'd rather new instruments to be used. Arnold's stuff is so repeatitive to me now. This was especially apparent when Craig does the gunbarrel shot - it's the intro drums that I've heard 1000 times before.
Personally, if we are doing a Bond restart, I'd ditch Arnold (his style just brings up memories of the bad DAD etc) and I'd also ditch Judi Dench as M. Then it would be more of a restart to me. I'm fine with Campbell for the moment (apart from refusing to dye Craig's hair).
