Playwright A. R. Gurney's technique in exploring 10 characters at a wayside in their lives is initially arresting: We see them in simultaneity, inhabiting the same motel room outside Boston. Of course, they don't inhabit the same room in reality, so we hear a lot of overlapping dialogue.
The production at the 21st Street Theater features generally well-etched performances, direction (by Gary Gardner) that deftly negotiates the necessary tricky staging and competent if rather washed-out set and lighting values.
The problem with the play is that once the fetching staging device has exhausted your interest--say, early in the second act--the play falls into a conventional pattern of only moderately gripping dramas. That makes it a wonderful test for the actors, however.
None here is weak and some turn ordinary dilemmas into solid craft: notably Sam O'Neal as a decently tacky husband looking for a one-night stand (a performance so truthfully forlorn you may overlook it altogether) and Carl Walsh as another burned-out case divorcing his wife. (A disconcerting miscue here is Walsh's stage wife, who is--ahem--too much older than he to make it a believable marriage.)
