Lone Survivor is a typically robust and exhausting action biopic from Peter Berg, who has made a career of documenting heroism and, in this case, seemingly impossible efforts to survive. Once we move through the somewhat tedious preamble, this is one of the more brutal and gruesome war films you're likely to encounter.
Berg's approach is workmanlike and no-frills (but certainly not no-thrills), as he captures the gritty and unrelenting intensity of a gunfight between the Taiwan and a team of SEALs outgunned and outgunned. The vulnerability of the characters is refreshing and it is easy to sympathise with the calamity of their plight.
Things get a bit overwrought in the final act, which unsurprisingly is the most embellished sequence of the film, but it's difficult not to get hooked on the adrenaline shot this movie provides. Ben Foster is great as always too, even with the limited scope of the role these actors are asked fo perform.
