Versatile, brutal and gritty - the right movie with the right Director and main actor. Guy Ritchie is well known by his frenzied and energetic filming style and this one not escape the pattern - as with Jake Gyllenhaal that is a well suited actor for action movies (ans strange to remember him in Donnie Darko and Brokeback Mountain to show as versatile as he can be).
Gritty and realistic story (not based on a single story but in a collective of stories of true events), where a US MArine saves a Afghan interpreter life after they fall behind enemy lines. Expect a more realistic and tense movie till the end - if you like war movies this is for you.
Filmed on Spain as the real territories of Middle East are dangerous to film into (with some exceptions as Jordania).
Engaging enough to link the emotional links between war translators (usually locals, that were observed closely) and their marine squads, it shows little pieces of both protagonists life's into a long and dangerous road toward rescue.
Score: 8,0 out of 10.0 / A-, as I am a fan of war movies.
