"Holloway created this fascinating, intermission-less play for the low-budget A Red Orchid Theatre in Chicago with a different cast and director in late 2019. A Red Orchid is an artistic petri dish where the actors work just a few feet from your head. Back then, it both scared the bejesus out of me and compelled me with its emotional intensity and psychological sophistication. And I had no idea where it was going.
On Broadway, where the expectations are as different as the beefed-up budget, both fresh polish and a palpable tension has emerged between the oddball core of this play and the need to play up to the commercial expectations surrounding a marketable world like horror. The show, now directed with his typical craft and creativity by Joe Mantello, first titillates its audience with loud, scary music and a theater that immediately plunges into darkness and then, as the play takes a very different, avant-garde turn, hopes they will switch gears and come along for the ride.
I’m not sure those are the right initial expectations to raise, just as I am not convinced everyone around me at the matinee I saw understood what was going on, not least because Holloway wrote a much stranger play than anything typical of this genre and he refuses to pander. Good for him, and for Mantello for backing this young writer all the way, but I bet there will be plenty of question marks on the audience feedback surveys. “Grey House” is weird and complicated, more Sam Shepard and Tracy Letts than King, and very much of the Chicago storefront school."
