"There can’t be many actors with both Tennessee Williams and Gilbert and Sullivan on their resume, but O’Neill’s portrait of the multiply wounded ex-athlete is a cocktail of bitterness and dry, resigned wit, wringing an amazing amount out of so few words.. it’s a tightrope O’Neill walks expertly."

(Or at least I was.)” The Stranger, by Chief Editor, Christopher Frizelle, RENT
