Since its theatrical release in late 2013, 'Lone Survivor', the story of a squadron of Navy SEALs and their attempt to be rescued while outmanned and outgunned in the heart of enemy territory, based on a book by the same name from author and subject of the story Marcus Luttrell, has become the first box-office hit of 2014.

Despite the financial success, the film has not been without its critics. "Lone Survivor" has been called "jingoistic" and "pro-war propaganda".  Salon.com's Andrew O'Hehir referred to the film as "war-porn", while LAWeekly.com's Amy Nicholson said the film portrayed the attitude of "brown people bad, American people good."

These harsh worded reviews have sparked backlash from fans of the movie.

Television and radio host Glenn Beck said he'd fly Amy Nicholson, writer of the LAWeekly review mentioned above, first class to his television studio if she would agree to read her critical review aloud to the book's author, Marcus Luttrel. Inboxes and Twitter accounts of those critical of the film have been flooded by supporters.

Despite the negative attention, the film's box-office popularity appears to be on the rise.

Film review website Rotten Tomatoes currently shows a 72-percent critic approval rating and a 90-percent audience approval rating for the film.
