"BAT*21" is above all an exceptionally well made and very worthwhile film based upon a remarkable true story. The action sequences have been brought to the screen with the deliberate intention of not glamourising the necessary depiction of violence (to do otherwise would have been a lethal miscalculation). This film is also able to depict Hambleton's rescue as being a far from easy proposition and you constantly find yourself wondering if the mission will have a successful resolution at all, especially in light of the fact Hambleton is about to find himself caught in an area which is going to be blanket bombed by the Strategic Air Command.
