Forgot to add--A+. Loved it. Saw it in 3D IMAX (real 15/70 IMAX, not the IMAX-lite screen--which, to be fair, can be quite nice too, but not as good as the real deal). I don't normally like 3D, but it was very well done here. The story was not groundbreaking but the cinematic experience made it worth going to the cinema rather than waiting to watch it at home (I have a pretty decent home cinema, so I don't go out to movies as much as I used to).
Even with the "inaccuracies", the film shines as cinema and is none the lesser for them. My favourite visit to the cinema in years.
