Query: A mediocre performance

I'm not too satisfied with this performance on DVD. The production is very static. (The poor acting doesn't help.) The singing is far below the standard of vintage Wagnerian performance. Levine and his band do better justice to the music. But on the whole, it is an uninspiring performance. Not that worthy to be presevered on video.
