The action scenes are really good. Close combat with extremely long shots in tight spaces. Sometimes it has a shooter video game feel to it. Hemsworth and the stunt team really showed of their skills. This movie is really more about close combat scenes, than crazy Hollywood stunts a la mission Impossible. Other than that, all the story is already in the title, which is fine for this type of movie. The actor, who played the boy was a wonderful casting choice. He was carrying the whole emotion of story. We'll be seeing more of him. Other characters were not drawn out. This movie is not for everyone, it is not well rounded, it's all action and no story. I personally enjoyed it though. I recommend this for viewers that like close combat action and martial arts movies.
