It's dark but loosely based on the story of Vitaly Kaloyev. He was a Russian man who was convicted of murdering the man who he believed was responsible for the tragic plane crash that killed his wife and two kids from the Bashkirian Airlines Flight 2937 and DHL Flight 611. The incident occurred on July 1, 2002, when the two planes crashed into each other in midair over the town of Ãœberlingen, Germany. I thought that Arnold Schwarzenegger performance was probably the best acting of his career. He portray's a real human emotion unlike his past films which were more character driven. If you like a good drama with great cinematography and are not turned off by the theme, check it out. It is worth your time. I bought the dvd. That is how much I liked it.
