Went to see the film 13 Hours: The Secret Soldiers Of Benghazi in the cinema Sunday afternoon; definitely worth the price of admission just for the cinematography and Special Effects. No spoilers, but like virtually every other "based on historical events" (and in this case specifically "This is a true story") movie, there are gaping holes in the historical record as it is portrayed on film. I'm not going to go into a long dissertation about the differences between written story and film story; leave it as stipulated that the two formats have mutually opposing criteria and thus there will always be a need to adapt a written record into the more compressed film format, and that that compression often is achieved by illustrating a condition with a fictionalized example that evokes the impact of the more complex actual events to a viewing audience in a reasonable period of viewing time.
Also, it is the height of stupidity to bring your personal ideology with you to any movie. Enjoy the show for what it is, then have fun dissecting it with your friends and commentariat afterwards. I guarantee you will have plenty of opportunity to rip it to pieces no matter who wrote, directed, or starred in it.
Ok, one tiny spoiler (paraphrased): "Shorts to a gunfight? That's a bold statement, brother."
Go see the movie in the theater if you possibly can. This is one of those films that really benefits from the big screen viewing environment.
