Bond (still) an anachronism shock

I went to see the new Bond last night and found it a bit hard to follow - visually and plot wise. On Comment is Free today, James Denselow says Bond is still an anachronism, specifically:

The ability to kill everyone in sight and disobey the orders of elected officials pursuing realist agendas is totally out of place in the multi-polar and highly unstable foreign policy environment of today.

I did find the plot a bit unlikely - and the "realist" element quite unrealistic. The main premise was that the US and UK would let a shadowy international conspiracy have its way because it suited them. A bit unlikely, especially when it becomes clear that the shadowy international conspiracy is (unsurprisingly) trying to pull off a con - quite a small one in the grand scheme of things. Do they really think they'll get away with it? More than once?

If you've seen the film, perhaps you'll know what I mean. If you haven't, I hope I've not spoilt it.
