This was a great autobiographical movie. Will Smith's performance was top notch. The movie did a pretty good job of showing how the NFL's current concussion protocol has come about and how they wouldn't listen at first. For all of the controversy surrounding the movie making the NFL a look bad, I think that a lot of the film's punches were pulled and a lot of stuff was just referred to instead of actually shown. Still a great watch though.
I would recommend people check this out. It's not a must see but Will Smith's performance is great and the movie is an enjoyable watch.
