Gorgeous to look at. Id be interested in looking at the storyboards for this as well..
Some of the pauses and theatrical flourishes like the crushed pavement impacts being repeated weren't to my taste but it was all executed really well. I did get pulled out of the story with the inital pause and the moron guards just standing. I was expecting paniced reactions when he tossed the grenade, or a cautious and confused inspection.
If the intent is they are just that stupid.. a shot of them smashing their faces into sharp objects for fun would go a long way explaning their reactions in that scene.
