Failure: A Love Story is a swift, sad-funny theater piece featuring three lovely sisters: giggly, luminous Nelly, athletic, swim-obsessed Jenny June, and patient, practical Gertie. Metaphorically, they could all be facets of a single, fascinating woman, as each, in turn, enjoys a passionate love affair with the same man. In the Catamounts' intellectually elegant production, the women were all beautifully portrayed — but as played by Trina Magness, Gertie seemed to embody the depths and sorrows of all three sisters. Magness imbued this character with a radiant, low-key warmth that centered the entire evening.
