PTSD always follows trauma. No traumatized person is “strong” enough to escape it. Yet, for complicated reasons, Post Traumatic Stress symptoms are too frequently off everyone’s radar, particularly the radar of the one suffering. The reasons are both straight out of the DSM-V and very individual. Jeff Bauman’s story in David Gordon Green’s powerful new film, Stronger, with Jake Gyllenhaal’s deeply moving performance as Jeff and Tatiana Maslany’s complex and engagingly real portrayal of his girlfriend, Erin Hurley, is a good place to start understanding what happens after trauma.
