Like 'Gone with the Wind,' 'War Horse' (a National Theatre of Great Britain and Lincoln Center co-production, at the Vivian Beaumont) is virtually critic-proof. The show—an epic tale of a boy and his horse, based on Michael Morpurgo’s 1982 children’s book, and performed by humans and puppets—is beyond dramaturgy, and it’s too big and emotional for anything as small as opinion. It’s a force of nature, or, more accurately, a show about the nature of man, which the co-directors, Marianne Elliott and Tom Morris, shape with the utmost control and artistry. Everything about it works, especially the animals—horses, birds, even a goose—which were created by the Handspring Puppet Company. (Actors manipulate the puppets to convey the animals’ souls.) In a way, the ambitious choreography of the piece—there are thirty-five actors in the cast—makes “War Horse” as much a dance work as a theatre piece. I don’t know who wins here, Thespis or Terpsichore, but why choose?
