This film was wonderful. Very entertaining despite the serious nature of the story, and very suspenseful throughout the film. So much suspense that at some points I actually got truly nervous for the characters even though I knew the outcome of the story already (it was, after all, written about in some detail in this 2007 WIRED article after Bill Clinton declassified the mission).
The story is based on a true story but like all Hollywood films based on true story, some things had to be changed for dramatic effect. Ben Affleck talks about some of these changes here. Still, this does not make it any less enjoyable as a film. In the end, I walked out of the theater wanting to see it again. It was simply a good and entertaining film. I highly recommend it.
