Today, I watched the movie, Concussion which is a 2015 American biographical sports drama thriller film directed and written by Peter Landesman, based on the expose “Game Brain” by Jeanne Marie Laskas, published in 2009 by GQ magazine. This movie is talking about Dr. Bennet Omalu (forensic pathologist) who fights against the National Football League trying to suppress his research on chronic traumatic encephalopathy (CTE) brain degeneration suffered by professional football players. Then, the professional football players keep going to suicide, so Dr. Bennet thinks to research the CTE. However, National Football League thinks this research to affect their profit and business. Thus, National Football League does some threat to Dr. Bennet and his wife. I think this movie to make us reflection. It is because Dr. Bennet wants to do the research of CTE to public, National Football League and government avoid him to do that and take the threat action to him. However, he doesn’t give up. I think that he isn’t the American, so he can objective see the CTE to make the future problem. Also, I think he is a good doctor in this movie too. I am afraid to play the rugby and football, after I watched this movie. The reason is that rugby and football are having many dangerous things and easily have the injuries. Finally, I will recommend other people to watch this movie. It is because this movie can make the discussion with friends.
