Peter Shaffer wrote Equus in the early seventies, when people were maybe less frequently assaulted by the toxic masculinity of antisocial teenage boys. (Maybe.) The violent motivations of awkward, creepy Alan Strang are presented as a mystery – why would a sensitive boy blind six horses with a steel spike? – but it’s hard to watch the play today without assuming that Strang is just a Gamergate troll born a few decades too soon. Epic Theatre Company’s octagonal staging involves minimal sets and costumes, with just an odd EDM soundtrack for mood. Eric Behr is good as talky Strang’s talky psychiatrist; Rico Lanni gives his all as wayward Alan, delivering the play’s hammier lines with total devotion.
