Concussion appears to be a serious matter sports drama based upon concussions about the linkage to playing football and brain damage. This is quite the typical sports drama which is based on real events as real people. It is clear that the studios and actors thought this film was Oscar worthy, but it ended up being a failure at that part not receiving any nominations. This film isn't bad but for one it is an acquired taste that many people are not seriously into, and as a result we have seen this film flop at the box office (which isn't a complete surprise).Will Smith's acting is good, as with the rest of the cast but overall it seems somewhat forgettable in the end. There are several intriguing moments in the film but as a whole, nothing in which we have not seen in sports drama's. Recommend but do not set your expectations too high.

Excellent actors, true story, incredible truth.... A very good movie! I appreciated a lot the figure of dr. Omalu and his obsession for justice and truth. Also his wife's role is great, two real Christian models. Suggested to those who are on truth's side.

Another "must see" movie that makes you actually THINK. In this world of CGI fantasies, non-stop porno, and never ending sequels, it's good to know that some producers, albeit it too small a number, actually believe that there's still stories out there with actual social impact and importance. This is one such film. I think Will Smith has truly grown as a serious actor over the years, with this as his crowning achievement, in my view. Great performances all around, with a special nod to a superb Albert Brooks in a fantastic supporting role. Great comics often make great serious actors, agreed?

I work professionally with individuals with concussions, including carrying out post-concussion assessments. Thus, this film was on my must-see list, but it felt a little bit obligatory for that reason. I was expecting kind of a dry, medical progress sort of story, with the scientific hero establishing new insights (and, of course, being recognized, sooner or later, for doing so). While that's kind of true in the final analysis, the story is actually about power and belief, including the struggle to change a system in which the very behaviours that create devastating brain injuries are glorified, celebrated --- and commercialized. That truth has few champions is a recurring story in every field of human endeavour, not just at the junction of science, healthcare and sports. But it is easy to forget how unpopular and unwelcome truth so commonly is, and the many reasons why this is so. On an additional note, Will Smith outdid himself in exhibiting his capacity to portray a character who is obviously not a mere variation of "himself." He succeeds at placing himself imaginatively into a character who is somewhat distinctive and, more than that, not at all a North American stereotype --- that is, a successful immigrant who had established much of his success before he ever got here, and was then stymied in the United States by cultural forces whose nature, ultimately, is alien to his own background and experience. In short, this was not a dry, scientific progress story; rather a gripping drama of struggle and hard-won victory --- and still only partially-won.
