I agree 100%. Excellent movie and very well presented. I double-checked the story behind it and the facts don't seem too far off.
The No. 4T did it's work and did it well. No over-the-top shooting or wild, unbelievable shooting around corners or glancing projectiles off surfaces to hit a target. Just hard work, very obviously dangerous in the extreme and so far from the usual movie nonsense as to make one believe it was a close portrayal of reality.
See it if you can.
