Concussions are the new cigarettes.
If you are interested in the depth of human denial or just in information about head injuries, this is a good documentary. It has a definite point of view about the need to do something about the huge problem of sports-induced concussions. But it also acknowledges the importance of sports as a process for mentoring and socializing youngsters, as well as protecting them from unsupervised time hanging around after school. And just the joy of sports.
Be warned that you will actually see brains being sliced (dead brains).
This is, of course, the perfect match to Concussion which is the biopic of Dr. Bennet Omalu, who was one of the first physicians to identify the immensity and intensity of the problem and to fight the entrenched interests of the NFL. You’ll see some film of Omalu in the documentary.
