Playwright Aaron Randolph III has, so far as I know, effectively captured the mental workings of a soldier suffering from post-traumatic stress disorder in his new drama A Green River. A representation of the chaotic, haunting thoughts likely experienced by some soldiers with PTSD, his play takes us through the memories of a single soldier - from childhood to falling in love to combat to his return home - while the young man revisits his favorite quiet place along a river. And as if the proceedings in Randolph's story weren't enough, he also includes a stunningly moving finale that packs such an emotional punch that I'd be surprised if most, if not all, of Saturday's audience members for the QC Theatre Workshop production aren't still reeling from it.
