Concussion

I thought this film was okay, though I wasn't quite all that interested in the Bennett Omalu home life side of the story as he slowly realizes that repeated head trauma from playing football causes a condition, CTE, that doesn't show up in scans on living human beings, but only confirmed after death via autopsies.

But it's still a sobering look at the human costs incurred playing football at a professional level where the tremendous amount of money made by the NFL threatened to sweep such revelations under the rug to preserve their cash cow at the expense of shortened lives of the players who create the entertainment value for the NFL.

I give it 2.75 stars, or a grade of B-. (also worth seeing if you are interested in seeing how the NFL finally had to create concussion protocols to keep concussed players from going back into the games and getting more hurt).
