‘Hir’ at Steppenwolf: In battle on home front, now a gender mine field, a Marine seeks cover

Review: Taylor Mac’s tumultuous, off-the-wall play “Hir,” currently on stage in a bristling production at Steppenwolf, is about battles, foreign and domestic. And if the shape-changing military one in the Middle East has been going on for a long time, the societal one at the center of “Hir” is just building a good head of steam. Ex-Marine Isaac has come home to a household in chaos, and to a new sexual order – a whole new declension of genders in which “he” and “she” are but instances on a daunting new landscape. ★★★★
