I'm a father of an autistic child, and I Can see my self and my son in this movie all the time. This is a great history that don't use stereotypes as genius children that can break complex codes or make complex mathematics operations in seconds for impress the audience, it is the story of a dying father making the impossible to give his son the possibility of independence before the cancer take his life. The performance of Jet Li as the father is remarkable, he lost him self in the character, and show us that he is an incredible actor. Wen Zhang makes an incredible job as the autistic son of Li, in some moments he makes my believe that he really was autistic. An incredible peace of art that must be running to an Oscar.
