‘The Weir’ at Irish Theatre: Ghosts and laughs abound — until hidden demons come to light

Review: It’s a play about hauntings, Conor McPherson’s “The Weir,” a dark and sharply drawn comedy of the unconscious now enjoying an infectious – and, happily, extended — run by the Irish Theatre of Chicago. Ghosts, the ones within us, fill the rural pub where “The Weir” unfolds: Five characters quite recognizably and sufficiently stand in for the lot of frail, erring, rueful humanity. ★★★★
