Concussion

I had the impression that risk of concussion among professional football players was controversial. If I can trust the accuracy of the movie "Concussion," there's no doubt of it: the risk is real and very dangerous.

Will Smith plays the part of Dr. Bennet Omalu, immigrant from Nigeria and very smart doctor. From his experience dealing with the premature deaths of some pro-football players, especially in Pittsburgh, he concludes that the many hits they take to the head lead to serious brain injury. 

Smith's performance in yet another very different sort of role for him is a pleasure to watch.
