Though the production too often feels as if it were designed for the company’s own edification — an endless rehearsal rather than a Broadway revival — it is not without its outward-facing qualities, especially after the initial throat-clearing. There are beautiful, quietly observed moments: a glance between Craig and Negga, for instance, that says more about marriage than some entire plays on the subject. There are smaller characters crystallized in a flash: Lazar’s Duncan dainty and handsy, Maria Dizzia’s Lady Macduff heartbreakingly resolute.
