Great film, but unfortunately it seems to have given all the moral guardians an excuse to pull out the soapbox and say the UK ratings system is too lenient, pointing at the higher ratings it got around the world (mostly 15s or 16s, compared to a UK 12A).
Bah, it will put the hairs on the chests of those <=12 year olds. Nothing wrong with a bit of mindless violence and burning carnage
