As @instudiocity indicated, Levine has sued the Met for a variety of things. In the meantime his successor, Yannick Nézet-Séguin, is building a rapport with singers and the orchestra that seems to match what I observed in the early days of Levine.
Interestingly, the conducting legend Gustavo Dudamel just mounted the Met podium for the first time with a well received run of Otello. He’s 37. He started conducting at La Scala at 25. One wonders if Levine is responsible for this unfortunate delay.
