Top notch war film, right up there with Blackhawk Down and Platoon. Aside from Amazon, I have seen many bad reviews written about this film. Don't believe them.
As far as facts go, the only person to criticize this film was the CIA chief who claimed that he never told his security contactors to stand down. The contractors eventually disobeyed his orders;
the 1/2 hour delay may have caused Ambassador Stevens his life.
The film moves at a fast pace & the combat & tactics give the movie a very realistic feel. These 6 contractors were ex-elite military with combat experience with the Marines, Navy Seals & Army Rangers. Greatly outnumbered, they displayed remarkable courage & professionalism under fire, despite the fact that they were not given their requested air support. The use of relatively unknown actors also adds to the realism.
I have very little to criticize this film. It has a gritty, unsanitized quality to it. It's about betrayal, selflessness, the chaos & confusion of combat & fighting for survival & the man next to you. Not for some ideology or political agenda. If you enjoyed movies like Platoon, Blackhawk Down, We Were Soldiers or HBO's Band of Brothers, you will like this movie. It can be viewed again & again.
