Unbroken is about this guy, Louie Zamperini, who was one of the Olympic runners before the WWII and how he managed to survive though the war. I would say this upfront; The film is quite bias against the Japanese since it is a biography of his time through the world war.
The flashback to Louie's childhood was quite unexpected as there was no warning given, but it gave us the information of how he became an Olympic runner. The battle scenes in the movie was not as gory as I thought it would be for a war movie; instead it was more of "Life of Pi" scenes when Louie and his army comrades were stranded out at sea.
I think it failed the horrors of war was not captured properly in the movie, and there are random shots when the actors look really healthy even though they were supposed to be malnourished. Only snippets of his life was captured and the ending was too abrupt for my liking; they didn't mention about the girl that he had married until the end of the film, and many details were omitted from the movie.
Would only recommend people to watch if they like biography movies. Otherwise, there are more movies out there which are better.
