Way too much of Deborah Voigt's Bruennhilde is just plain embarrassing: pitchy, terrible or nonexistent enunciation (she is just not bothering with a shocking number of words), rushing, lunging at notes, poor connection with her lower register, etc., etc. She should be singing in the Sieglinde / Gutrune league, not Bruennhilde.
Also, I see why people wish Luisi had more weight in his conducting. The coda needs more majesty and more time to unfold than he is giving it. Why the big rush, Fabio?? You've got one of the greatest orchestras in the world in front of you. Slow down and let them enjoy themselves a bit more.
