By John Keegan and Edmund BoysAfter physically injuring half the cast last time, “The Newsroom” subjects the rest to lashings of the mind. In addition to recycled dialogue, the reluctant, or inadvertent, therapy session has been a Sorkin staple, from Dan’s thera-dates on “Sports Night” to Adam Arkin’s sessions on “The West Wing”.
