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.

A reasonably important movie to warn people (especially parents) about the danger of head related injuries from combat-style sports. And it does veer into the usual Hollywood conspiracy type movie of big bad organizations trying to suppress the knowledge from people.However, one important fact, Dr. Bennett Omalu didn't discover or name Chronic Traumatic Encephalopathy as claimed in the movie. Although he was probably most responsible for extending it to American style football in his 2006 paper."CTE was originally studied in boxers in the 1920s as dementia pugilistica. The seminal work on the disease came from British neurologist Macdonald Critchley, who in 1949 wrote a paper titled "Punch-drunk syndromes: the chronic traumatic encephalopathy of boxers." CTE was first recognized as affecting individuals who took considerable blows to the head, but was believed to be confined to boxers and not other athletes." (Wikipedia) Also not mention is that in has impacted players in wrestling, ice hockey, mixed martial arts, soccer, Rugby, Australian rules football, baseball, and extreme (BMX) sports. (Wikipedia)

A splendid, uplifting movie, focusing on the scientific intelligence and courage of Dr Omalu, who discovered the effects of concussion on football players, which was named CTE. Will Smith does a great job as the doctor, as enjoyable as his performance in The Pursuit of Happiness.The actress who plays his wife is also excellent. When he wavers in facing the forces trying to silence him, she reminds him his name is Omalu Onyemalukwube: "if you know, you must come forth and speak."Supporting actors, including Alec Baldwin, do a good job as well. Highly recommended, and a topic that every parent should be aware of.
