The language of playwright Tracy Letts' August: Osage County is loaded with layers of emotion underneath its dialogue. During New Ground Theatre's opening performance on Friday, a few actors neglected the dark undertones, reciting their lines as if Letts' words held nothing below the surface. Most, however, got to the heart of the script, impressively revealing the richness of the work through performances that ranged from subtle to over-the-top. While not perfect, the show deserved the standing ovation it got from the audience.
