This is a spoiler free review. Its more about impressions than the storyline.
And the 1st impression is one of tight, disciplined editing. There is nothing extraneous in the storyline; all shotguns on the mantlepiece are used and don’t usually get much time to gather dust whilst they’re waiting to be fired.
The 2nd impression is that the tight editing vastly improves the character development, and enhances the general “War on Terror” atmosphere of the story.
All in all, a very impressive piece of work.
EDIT: A couple of amusing items in the end credits (alas no easter eggs, sys admins, or business analysts):
a) Drapesmasters. What the…?
b) Wand Combat Choreographers
(Note the plural in both cases)
