The new ballet is emotionally direct, superbly choreographed, and beautifully staged. It’s a full reinvention — new score and all — yet the story and its spirit stay faithful to Pushkin. Rating: ⭐️⭐️⭐️⭐️⭐️⭐️ — the extra ⭐️ for a modern recreation of a classic that doesn’t fall apart just because the director wanted to flash some avant-garde nonsense. ...
