Director Arin Arbus has staged a relatively faithful and straightforward rendition, which is probably for the best since the playwright’s estate tends to take a dim view of any radical reinterpretations. A bare stage with the familiar leafless tree provides the setting, although it here takes the form of a long catwalk-like strip made to look like a desolate highway, with a painted line down the center. As we enter the theater, Shannon’s Estragon sits onstage, doing, what else, waiting. Except in this case for the show to begin.
