A marksman living in exile is coaxed back into action after learning of a plot to kill the president. Ultimately double-crossed and framed for the attempt, he goes on the run to track the real killer and find out who exactly set him up, and why.
I'm going through a kind of action phase right now and Fuqua is the dude with the best of the bunch: Training Day, Brooklyn's Finest and this. Yes, as Michael said below it is a well made action film nothing more nothing less.
A case of "could-have-been" if not for some terrible conveniences in the plot and cliche fodder. Retribution agains a rotten power by a polluted ex citizen is ripe material and Shooter may have even risen to the height of a modern First Blood. I'm a Wahlbergist so I was on Mark's marksmanship, but boring Hollywood devices broke the film's back.
If having a protagonist with an awesome name led to having an awesome movie, Bob Lee Swagger would've made Shooter the film of the decade. As it stands, it's a pretty crummy film outside of a few cool action bits.
