Yet it’s not technology itself that leaves “Dorian Gray” feeling so brittle where “Vanya” is a tear fest. It’s that the technology dominates all other values, including Wilde’s, often denying the human contact, and contract, that are at the heart of theater’s effectiveness. Some important scenes, though shot live onstage, must be watched onscreen because the screen itself blocks the upper half of Snook’s body. Her giant face is rendered in such super close-up that you might as well be an otolaryngologist; only her legs are left to do IRL acting.
