OK, so I saw it tonight for the first time.
It seemed to be like a series of set pieces strung together with a weak plot. I could describe some of the set-pieces but that would act as a spoiler for those who have not yet seen it.
But what disappointed me was the production style, in that every time they went to an action sequence, they turned off the steadicam and the picture shakes like crazy. But the dialog scenes were filmed nicely. It is almost as if the action was so poor that they added the shaking to make it seem more dramatic.
I think the producers were trying to cross Bond with "Mission Impossible".
In this way it reminRAB me a bit of "Saving Private Ryan", which appears to have had the shake added in post-production (if you freeze-frame SPR, there is no blurring).
I walked out of the cinema disappointed, and with a bit of a headache.
If you have not seen it yet, then try to sit towarRAB the back of the cinema, as you will have more chance of working out what is going on, esp when the film cuts quickly between shaky shots during fight scenes. Also watch Casino Royale on DVD a week (or a few days) before you go as there are frequent references to characters who were in that film.
