Because, like Dead Poet’s Society, this understated, ’80s-style movie packs quite a punch (emotionally speaking).
Because Timothy Hutton, Donald Sutherland, Judd Hirsch, and Mary Tyler Moore are star performers in their respective roles.
Because you feel for them (except for Moore as the mom), and feel with them (except the mom), and cry with them (except the mom), more than you probably should since it’s fictional. Then again, maybe not, since it’s a very real reflection of real life events and consequences.
