LOWELL — Watching Merrimack Repertory Theatre’s production of David Mamet’s “Glengarry Glen Ross’’ is a double-edged experience.
You feel the inward glow of satisfaction that comes from seeing a great play directed with insight and performed by a skilled ensemble. But you also feel a pang as you consider how many years it’s been since the playwright wrote anything nearly as good. It’s like seeing archival footage on ESPN of a no-hitter by a pitcher who has long since lost his fastball.
Merrimack Rep’s topnotch production of “Glengarry Glen Ross,’’ directed by Charles Towers, brings us back to a time before Mamet’s style calcified into mannerism, before he began to turn out gnarled, willfully opaque dramas.
