Gripping military dramas based on true events have proven to be a very popular subgenre in Hollywood throughout the 21st Century, although the results have been decidedly mixed. The Hurt Locker found plenty of awards season glory while Zero Dark Thirty, Lone Survivor and Black Hawk Down scored solid box office business and enthusiastic reviews, but lying at the other end of the spectrum are the painfully mediocre likes of Michael Bay's 13 Hours and Chris Hemsworth vehicle 12 Strong.
