Tonys 2008: ‘The Farnsworth Invention’ lacks originality
TV and movie scribe Aaron Sorkin’s return to Broadway 18 years after triumphing with the military courtroom drama "A Few Good Men" was met with a collective critical shrug. Reviews for the strike-delayed opening of "The Farnsworth Invention" — a historical drama about the birth of television — range from bad to mediocre, albeit with one notable exception. This hoped-for awards contender in a busy season of play premieres may find itself forgotten, if not gone, come Tony time next June.
