Throughout Samuel D. Hunter's play The Whale, at Playwrights Horizons in 2012, the main character is a gay man isolating himself by virtue of his obesity. Now back at PH with Pocatello, Hunter watches -- in a series of highly animated scenes -- another gay man who's isolating himself and has been isolated. Which condition came first is, like the chicken or egg, unclear.
A director's work is often tricky to review on the basis of one production -- in the case of a first work, it is often unclear what is a director's idea versus what is a stage direction in the script itself. It is also hard for people to separate actors' choices from a director's touch. But after a period of watching a director's work, you get it.
