It’s surprising that Ah, Wilderness! doesn’t get done more often. Eugene O’Neill’s only full-length comedy—not, he later said, an autobiography, but a look back at the teen years he wished he’d had—the gentle two-acter is warmhearted, smart about intergenerational conflict, and extremely influential. It’s the template for every stage family comedy from You Can’t Take It With You to Morning’s at Seven and beyond, not to mention countless TV sitcoms, up to and including Modern Family. It rings with universal truths that are easy to identify with, and it’s not hard to stage.
