Peter Landesman's historically based Parkland raises many questions but none about the event at the center of this film -- the assassination of President Kennedy. The main question it raised for me is what did Landesman hope this film, his directorial debut, would be? It doesn't seem to have a unifying idea or premise for the audience to ponder or respond to. It's just sad recreation of a sad day for our country. Named for the hospital where Kennedy was taken after the shooting, the film is a collection of characters swirling around the action -- medical personnel, Secret Service and FBI agents, Dallas police, members of the presidential motorcade -- but also Abraham Zapruder, whose home movie at Dealy Plaza captured the assassination, and accused assassin Lee Harvey Oswald, his brother and his mother. There are far too many people for the movie's 93 minutes, and no emotional investment in any of them despite having some pretty solid Hollywood wattage in Paul Giamatti as Zapruder and Billy Bob Thornton as special agent Forrest Sorrells.
