It has an interesting concept but doesn't live up on the execution. After a few times of rewinding to the exact same starting point for the purpose of putting the puzzles together from multiple angles (again, sounds conceptually interesting), it gets a bit tiresome. Bland performances, zero character development, outlandish key elements, absurd resolution. If you're expecting an intellectual political thriller, this is not it. It is a thrill, however. Frenetic pace, foot & car chases (reminding you of the style and implausibility of the "Bourne" series, "The Italian Job," "Live Free Die Hard"), gun shots and explosions. Actually enjoyed the last two-third tremendously - when it shifted into high gear (starting w/ Forest Whitaker's vantage point) and the actions never let up till the end.
