Will Smith's latest film has hit thearter's and here's one reviewer's thoughts. When retired Pittsburgh Steelers center, and Hall of Famer, Mike Webster (David Morse) commits suicide, after months of erratic behavior, his body comes before Nigerian-born forensic neuropathologist Dr. Bennet Omalu ( Will Smith). Charged with determining the true cause of Webster?s death, the affliction that lead to the Football player?s descent into mental instability, Omalu formulates a theory: repeated blows to the head, as experienced by football players over a decade on the field, irreversibly damages the brain ? leading to dangerous mental impairments (depression, anxiety, memory loss, and aggression, among other symptoms). Concussion isn?t a great biopic but it tells a great story ? thanks to stirring subject matter and a quality performance from Will Smith.
