Anyone watched the documentary Concussed?

Watching the documentary called 'Concussed'. Just wonder if anyone else has watched it? I think it's well done so far. I had hoped CTE would get more exposure because of it but I guess money talks. I do like that Goodell gets exposed as an arse-hat. Also found it ironic that the 49ers delivered one of the most vicious blindside blocks against the the main guy in the film (where have we seen that type of playoff behavior from them before?) Also found the Billy Joe Tolliver/Favre story amusing. All in all... pretty gut wrenching documentary
