Repeated several times over the course of 90 minutes, that cycle - enhanced by Chavkin’s pacing, which leaves you swallowing your laughter - can lead to an upset stomach. And the characters are sometimes so exaggerated for satire that they lose their grip on your emotions. Still, by the time the bloody tale of the Pequot massacre is enacted onstage, you may find yourself agreeing with Logan, of all people. Being a vegan, she already struggles with the “holiday of death”; I wanted to disown it entirely, from the turkeys all the way back to the Pilgrims. But “The Thanksgiving Play” is not primarily a brief for correcting American history. Like Tracy Letts’s “The Minutes,” which also uncovered a horrific massacre hiding in the clothing of civic pageantry, FastHorse is interested in how new information (new only to some people) might change the stories we tell in the future. The first step, to judge by the absurd crew onstage, will be to change the storytellers. FastHorse being the first Native American woman known to have a play produced on Broadway, maybe we’ve finally started.
